MC68HC11FTS/D
For DDRx bits, 0 = input and 1 = output.
NOTE
When the SPI system is in slave mode, DDD5 has no meaning or effect. When the
SPI system is in master mode, DDD5 determines whether bit 5 of PORTD is an er-
ror detect input (DDD5 = 0) or a general-purpose output (DDD5 = 1). If the SPI sys-
tem is enabled and expects one or more of bits [4:2] to be inputs, those bits will be
inputs regardless of the state of the associated DDR bits. If one or more of bits [4:2]
are expected to be outputs, those bits will be outputs only if the associated DDR
bits are set.
U = Unaffected by rest.
PORTE is an input-only register. Reads return the digital state of the I/O pins, and writes have no effect.
On the MC68HC11F1, port E is shared with the analog-to-digital converter. (The A/D converter is not
present on the MC68HC11FC0.)
GWOM — Port G Wired-OR Mode Option
This bit affects all port G pins together.
0 = Port G outputs are normal CMOS outputs
1 = Port G outputs act as open-drain outputs
NOTES:
1. These bits are not present on the MC68HC11FC0 and will always read zero.
2. This bit is not present on the 64-pin QFP version of the MC68HC11FC0 and will always read zero.
