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 (IIL, 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

P1.2 / SCLK

P1.3 / SRI

P1.4 / STO

P1.5 / SLS
