8.6.12 Precautions when using multi-master
I2C-BUS interface
(1) Read-modify-write instruction
Precautions for executing the read-modify-write instructions, such
as SEB, and CLB, is for each register of the multi-master I2C-BUS
interface are described below.
I2C data shift register (S0)
When executing the read-modify-write instruction for this register
during transfer, data may become an arbitrary value.
I2C address register (S0D)
When the read-modify-write instruction is executed for this register
at detection of the STOP condition, data may become an arbitrary
______
value. Because hardware changes the read/write bit (RBW) at the
above timing.
I2C status register (S1)
Do not execute the read-modify-write instruction for this register
because all bits of this register are changed by hardware.
I2C control register (S1D)
When the read-modify-write instruction is executed for this register
at detection of the START condition or at completion of the byte
transfer, data may become an arbitrary value because hardware
changes the bit counter (BC0–BC2) at the above timing.
I2C clock control register (S2)
The read-modify-write instruction can be executed for this register.
(2) START condition generating procedure us-
ing multi-master
Procedure example (The necessary conditions for the procedure
are described in to below).
LDA
—
(Take out slave address value)
SEI
(Interrupt disabled)
BBS 5,S1,BUSBUSY
(BB flag confirmation and branch pro
cess)
BUSFREE:
STA S0
(Write slave address value)
LDM #$F0, S1
(Trigger START condition generation)
CLI
(Interrupt enabled)
BUSBUSY:
CLI
(Interrupt enabled)
Use “STA,” “STX” or “STY” of the zero page addressing instruc-
tion for writing the slave address value to the I2C data shift register.
Use “LDM” instruction for setting trigger of START condition gen-
eration.
Write the slave address value of and set trigger of START con-
dition generation as in continuously, as shown in the procedure
example.
Disable interrupts during the following three process steps:
BB flag confirmation
Write slave address value
Trigger of START condition generation
When the condition of the BB flag is bus busy, enable interrupts
immediately.
