12.9.1 - Alternate Functions of Port 6
A programmable number of chip select signals (CS4...CS0) derived from the bus control registers
(BUSCON4...BUSCON0) can be output on 5 pins of Port 6.
The number of chip select signals is selected via PORT0 during reset. The selected value can be read
from bit-field CSSEL in register RP0H (read only) in order to check the configuration during run time.
The Table 19 summarizes the alternate functions of Port 6 depending on the number of selected chip
select lines (coded via bit-field CSSEL).
