1.5.5 Port B (PB5/SDO, PB6/SDI, and PB7/SCK)
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 7. Input/Output (I/O) Ports and
1.5.6 Port C (PC0–PC2, PC3/AD3, PC4/AD2, PC5/AD1, PC6/AD0, and PC7/VREFH)
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
1.5.7 Port D (PD5/CKOUT and PD7/TCAP)
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 Section 7.
NOTE:
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.
1.5.8 Timer Output Compare (TCMP)
TCMP is the output from the 16-bit timer’s output compare function. It is
low after reset. Refer to Section 8. 16-Bit Timer.
