I/O Port 1
Port 1 is an 8-bit quasi-bidirectional port with internal
pull-up arrangement. Port 1 pins that have “1s”
written to them are pulled high by the internal pull-up
transistors and in that state can be used as inputs.
As inputs, Port 1 pins being externally pulled low will
source current (
I
, in the DC characteristics)
because of the internal pull-up transistors.
The output latch corresponding to a secondary
function must be programmed to 1 for that function
to operate.
For the outputs of the Synchronous Serial Channel
(SSC), SCLK and STO, special circuitry is
implemented providing true push-pull capability.
The STO output, in addition, will have true tristate
capability. When used for SSC inputs, the pull-up
transistors will be switched off and the inputs float
(high ohm inputs).
The secondary functions are assigned to the pins of
Port 1 as follows:
P1.0 / T2
P1.1 / T2EX
Input to Counter 2
Capture/reload trigger of Timer 2
Up-Down count
SSC Master Clock Output
SSC Slave Clock Input
SSC Receive Input
SSC Transmit Output
Slave Select Input
P1.2 / SCLK
P1.3 / SRI
P1.4 / STO
P1.5 / SLS
