Description
T0OUT
T1OUT
O
D
H(Q)
R(1)
P(Q)
Timer OUTput
pins can be programmed to provide a
single clock or continuous waveform generation,
depending on the timer mode selected.
T0IN
T1IN
I
A(L)
A(E)
D
Timer INput
is used either as clock or control signals,
depending on the timer mode selected.
INT0
INT1
INT4
I
A(E,L)
D
Maskable
INTerrupt
input will cause a vector to a
specific Type interrupt routine. To allow interrupt
expansion, INT0 and/or INT1 can be used with
INTA0 and INTA1 to interface with an external slave
controller.
INT2/INTA0
INT3/INTA1
I/O
A(E,L)
H(1)
R(Z)
P(1)
These pins provide a multiplexed function. As inputs,
they provide a maskable
INTerrupt
that will cause
the CPU to vector to a specific Type interrupt routine.
As outputs, each is programmatically controlled to
provide an INTERRUPT ACKNOWLEDGE
handshake signal to allow interrupt expansion.
P2.7
P2.6
I/O
A(L)
H(X)
R(Z)
P(X)
BI-DIRECTIONAL, open-drain
Port
pins.
CTSO
P2.4/CTS1
I
A(L)
D
Clear-To-Send
input is used to prevent the
transmission of serial data on their respective TXD
signal pin. CTS1 is multiplexed with an input only port
function.
TXD0
P2.1/TXD1
O
D
H(X)/H(Q)
R(1)
P(X)/P(Q)
Transmit Data
output provides serial data
information. TXD1 is multiplexed with an output only
Port
function. During synchronous serial
communications, TXD will function as a clock output.
RXD0
P2.0/RXD1
I/O
A(L)
R(Z)
H(Q)
P(X)
Receive Data
input accepts serial data information.
RXD1 is multiplexed with an input only
Port
function.
During synchronous serial communications, RXD is
bi-directional and will become an output for
transmission or data (TXD becomes the clock).
P2.5/BCLK0
P2.2/BCLK1
I
A(L)/A(E)
D
Baud CLocK
input can be used as an alternate clock
source for each of the integrated serial channels.
BCLKx is multiplexed with an input only
Port
function,
and cannot exceed a clock rate greater than one-half
the operating frequency of the processor.
P2.3/SINT1
O
D
H(X)/H(Q)
R(0)
P(X)/P(X)
Serial INTerrupt
output will go active to indicate
serial channel 1 requires service. SINT1 is
multiplexed with an output only
Port
function.
NOTE:
Pin names in parentheses apply to the 80C188EB/80L188EB.
