I/O
Port 1
is an 8-bit quasi-bidirectional port with internal pull-up ar-
rangement. Port 1 pins can be used for digital input/output
or as analog inputs of the A/D converter. Port 1 pins that
have 1’s written to them are pulled high by internal pull-up
transistors and in that state can be used as inputs. As in-
puts, port 1 pins being externally pulled low will source cur-
rent (
IIL, in the DC characteristics) because of the internal
pullup transistors. Port 1 pins are assigned to be used as
analog inputs via the register P1ANA.
As secondary digital functions, port 1 contains the interrupt,
timer, clock, capture and compare pins. The output latch
corresponding to a secondary function must be pro-
grammed to a one (1) for that function to operate (except for
compare functions). The secondary functions are assigned
to the pins of port 1 as follows:
P1.0 / AN0 / INT3 / CC0
Analog input channel 0
interrupt 3 input /
capture/compare channel 0 I/O
P1.1 / AN1 / INT4 / CC1
Analog input channel 1/
interrupt 4 input /
capture/compare channel 1 I/O
P1.2 / AN2 / INT5 / CC2
Analog input channel 2 /
interrupt 5 input /
capture/compare channel 2 I/O
P1.3 / AN3 / INT6 / CC3
Analog input channel 3
interrupt 6 input /
capture/compare channel 4 I/O
P1.4 / AN4
Analog input channel 4
P1.5 / AN5 / T2EX
Analog input channel 5 / Timer 2
external reload / trigger input
P1.6 / AN6 / CLKOUT
Analog input channel 6 /
system clock output
P1.7 / AN7 / T2
Analog input channel 7 /
counter 2 input
Port 1 is used for the low-order address byte during program
verification of the C505-2R and C505C-2R.
