TECHNICAL DATA
I4/O5 — Configure TI4/O5 register for IC4 or OC5
0 = OC5 function enabled
1 = IC4 function enabled
RTR[1:0] — Real-Time Interrupt (RTI) Rate
6.5 Parallel I/O Control Register (PIOC)
PIOC configures and controls handshake I/O functions in MCUs where this function is
available. In the MC68HC11D3, however, only the CWOM bit in the PIOC register is
usable. The CWOM bit is cleared so that port C is not in wired-OR mode.
CWOM — Port C Wired-OR Mode (affects all eight port C pins)
0 = Port C outputs are normal CMOS outputs
1 = Port C outputs are open-drain outputs
PIOC— Parallel I/O Control
