Data Sheet
P6PUDEN (FE92
P6PHEN (FE94
8.6.1
A programmable number of chip select signals (CS3...CS0) derived from the bus control
registers (BUSCON3...BUSCON0) can be output on 4 pins of Port 6. The other 3 pins
may be used for bus arbitration to accomodate additional masters in a C161U system.
The number of chip select signals is selected via PORT0 during reset. The selected
value can be read from bitfield CSSEL in register RP0H (read only) eg. in order to check
the configuration during run time.
Table 30 summarizes the alternate functions of Port 6 depending on the number of
selected chip select lines (coded via bitfield CSSEL).
