Special Mode Combination Considerations
There are several combinations of modes possible. For any
combination, some or all of Port C lines are used for control
or status. The remaining bits are either inputs or outputs as
dened by a “Set Mode” command.
During a read of Port C, the state of all the Port C lines,
except the ACK and STB lines, will be placed on the data
bus. In place of the ACK and STB line states, ag status will
appear on the data bus in the PC2, PC4, and PC6 bit
positions as illustrated by Figure 25.
Through a “Write Port C” command, only the Port C pins
programmed as outputs in a Mode 0 group can be written.
No other pins can be affected by a “Write Port C” command,
nor can the interrupt enable ags be accessed. To write to
any Port C output programmed as an output in a Mode 1
group or to change an interrupt enable ag, the “Set/Reset
Port C Bit” command must be used.
With a “Set/Reset Port C Bit” command, any Port C line
programmed as an output (including IBF and OBF) can be
written, or an interrupt enable ag can be either set or reset.
Port C lines programmed as inputs, including ACK and STB
lines, associated with Port C fare not affected by a “Set/
Reset Port C Bit” command. Writing to the corresponding
Port C bit positions of the ACK and STB lines with the “Set/
Reset Port C Bit” command will affect the Group A and
Group B interrupt enable ags, as illustrated in Figure 25.
