MOTOROLA
The TCMP pin is the output compare pin for the on-chip
capture/compare timer. See
These eight I/O lines comprise port A, a general-purpose, bidirectional
I/O port. The pins are programmable as either inputs or outputs under
software control of the data direction registers. See
These eight I/O pins comprise port B, a general-purpose, bidirectional
I/O port. The pins are programmable as either inputs or outputs under
software control of the data direction registers. Port B pins also can be
configured to function as external interrupts. See
These eight I/O pins comprise port C, a general-purpose, bidirectional
I/O port. The pins are programmable as either inputs or outputs under
software control of the data direction registers. PC7 has a high current
sink and source capability. See
These seven lines comprise port D, a fixed input port. All special
functions that are enabled (SPI and SCI) affect this port. See
