Enter stop mode. Not set until all pins of P0 and P1 are high.
Enter sleep mode. Released by WDT reset.
Enable flag of WDT. If this flag is cleared, WDT stops running and holds the state.
This flag can be modified if and only if MAP1 bit is set and MAP0 bit is cleared.
This flag is also set by H/W when user sets SLEEP flag or writes IAPCON SFR.
Reset Watch Dog Timer. Set by S/W. Cleared by H/W after WDT is reset.
Address map extension bit 1 for SFR/IFF.
Address map extension bit 0 for SFR/IFF. Do not set this flag for the future compatibility.
