MOTOROLA
NOTE:
Port B is comprised of three I/O pins which are shared with the SIOP
communications subsystem. The state of any pin is software
programmable and all port B lines are configured as inputs during
power-on or reset. Refer to
Section 9. Serial Input/Output Ports
Port C is comprised of eight I/O pins which are shared with the A/D
converter subsystem. The state of any pin is software programmable
and all port C lines are configured as inputs during power-on or reset.
Port pins PC0 and PC1 are capable of sourcing and sinking high
currents. Refer to
Port D is comprised of two I/O pins and one of them is shared with the
16-bit timer subsystem. The state of PD5/CKOUT is software
programmable and is configured as an input during power-on or reset.
PD7 is always an input; it may be read at any time, regardless of the
mode of operation the 16-bit timer may be in. Refer to
Input/Output (I/O) Ports
A mask option turns the PD5/CKOUT pin into a clock output which is a
buffered OSC2 signal with a CMOS output driver. The clock output or the
port D function must be chosen with the mask option and is not alterable
in software.
TCMP is the output from the 16-bit timer’s output compare function. It is
low after reset. Refer to
