The port 0, port2, port3.6 and port3.7 can be used as general purpose I/O pin while port0 is open-drain structure.
System Control Register (SCONF, $BF)
WDR : Watch Dog Timer Reset.
OME : 3840 bytes on-chip RAM enable bit
ALEI : ALE output inhibit bit, to reduce EMI
Setting bit 0 (ALEI) of SCONF can inhibit the clock signal in Fosc/6Hz output to the ALE pin.
The bit 1 (OME) of SCONF can enable or disable the on-chip expanded 3840 byte RAM. The default setting of OME bit is
0 (disable).
The bit 7 (WDR) of SCONF is Watch Dog Timer Reset bit. It will be set to 1 when reset signal generated by WDT overflow.
User should check WDR bit whenever un-predicted reset happened.
