x = unknown, u = unchanged, – = unimplemented locations read as ‘0’. Shaded cells are not used by PORTC.
RC4/C2OUT/P1B
Enabling both C2OUT and P1B will cause
a conflict on RC4 and create unpredictable
results. Therefore, if C2OUT is enabled,
the ECCP can not be used in Half-Bridge
or Full-Bridge mode and vice-versa.
