ST92163 - USB PERIPHERAL (USB)
USB INTERFACE (
Cont’d
)
8.3.4 Register Description
USB registers can be divided into three groups:
– Common registers (page 15): interrupt registers
and USB control registers.
– Function and endpoint registers (pages 15, 4
and 5 depending on how many
endpoints are im-
plemented): USB function addresses and end-
point status/configurations.
– Extra registers (page 60): device configuration.
8.3.4.1 Common registers
These registers affect all endpoints in the USB in-
terface. They are all mapped in the same ST9 reg-
ister page (page number 15).
The USB interface implements vectorized inter-
rupts: through a vector table it is possible to auto-
matically identify the starting address of each In-
terrupt Service Routine. The vector table contains
the 16-bit addresses pointing to each of the inter-
rupt service routines related to the CTR interrupt
for each endpoint. Other two 8-bit locations are
used to store the address of the service routine
handling the interrupts described in the USBISTR
register. When an interrupt request is acknowl-
edged, the USBIVR register provides a vector
pointing to the location in the vector table, contain-
ing the start address of the interrupt service rou-
tine related to the serviced interrupt.
INTERRUPT VECTOR REGISTER (USBIVR)
R248 - Read/Write
Register page: 15
Reset Value: xxxx xxx0 (xxh)
This register may be used in two different ways de-
pending on the value of the SDNAV bit in the
CTRL register.
– If SDNAV bit = 1, Bits 7:1 are user programmable
(bit 0 is fixed to 0). The software writes the ad-
dress of a vector pointing to a single interrupt
routine. The application program has to select
the routine related to the pending interrupts using
the USBISTR and CTRINF registers.
– If SDNAV = 0, this register is used as a vector
pointing to the 16-bit interrupt vectors in program
memory containing the start addresses of the in-
terrupt service routines related to the occurred
interrupt. If several interrupts are simultaneously
pending, hardware writes in this register the in-
terrupt routine address related to the highest pri-
ority pending interrupt.
In this case the meaning of each bit is:
Bits 7:6 =
A[1:0]:
Vector table Address.
These two bits are user programmable and they
contain the two most significant bits of the interrupt
vector table. This allows the user to define the in-
terrupt vector table position inside the first 256 lo-
cations of program memory at 64 bytes boundary.
Bit 5 =
CTRO
:
Correct Transfer interrupt occurred
.
0: No CTR interrupt pending
1: One of the interrupt flags in the USBISTR regis-
ter is pending
Note:
If several interrupts are simultaneously
pending, hardware writes this bit according to their
relative priorities as listed below starting from the
highest priority one to the lowest priority one:
–
DMA Over/Underrun (see
Table 26
and USBIS-
TR register description)
– Correct Transfer on isochronous endpoints (see
EPnRA register description)
– Correct Transfer on non-isochronous endpoints
(see EPnRA register description)
–
Notification events (see
Table 26
and USBISTR
register description).
Bits 4:1 =
V[3:1]
:
Endpoint Vector
.
If CTRO = 1, these bits are written by hardware to
specify the endpoint identifier which has generat-
ed the CTR interrupt request.
If several CTR interrupts are pending, hardware
writes the endpoint identifier related to the end-
point with the highest priority. Endpoint priority is
defined according to the following rule: endpoint 0
has the highest priority, then endpoint 1 follows
and so on up to the highest endpoint register pair
(EP15) with the lowest priority.
If CTRO = 0, these bits are fixed to 1. In this case
only one interrupt vector is used for all the inter-
rupts defined in the USBISTR register.
