6.9 Parallel I/O Control Register
M68HC11E Family — Rev. 3.2
MOTOROLA
Address:
The parallel handshake functions are available only in the single-chip
operating mode. PIOC is a read/write register except for bit 7, which is
read only.
STAF — Strobe A Interrupt Status Flag
STAI — Strobe A Interrupt Enable Mask Bit
CWOM — Port C Wired-OR Mode Bit (affects all eight port C pins)
HNDS — Handshake Mode Bit
Reset:
Read:
Write:
STAF is set when the selected edge occurs on strobe A. This bit can
be cleared by a read of PIOC with STAF set followed by a read of
PORTCL (simple strobed or full input handshake mode) or a write to
PORTCL (output handshake mode).
It is customary to have an external pullup resistor on lines that are
driven by open-drain devices.
0 = No edge on strobe A
1 = Selected edge on strobe A
0 = STAF does not request interrupt
1 = STAF requests interrupt
0 = Port C outputs are normal CMOS outputs.
1 = Port C outputs are open-drain outputs.
0 = Simple strobe mode
1 = Full input or output handshake mode
