1. Digital I/O pin function provided by port replacement unit.
2. Writing PCDPA = 1 has an undefined pin operation for D[31:16] and EB[3:2] in single-chip mode.
3. This pin functions as the reset configuration override enable (RCON) during reset.
4. Writing PEPAx = 1 has an undefined pin operation for port E pins in single-chip mode.
5. CSENx has no effect on selecting CS[3:0] pin function in single-chip or emulation modes.
