Bit 6~2: Reserved. Software must write “0” on these bits when XPIE1 is written.
Bit 1: EPCA, Enable PCA interrupt.
0: Disable PCA interrupt.
1: Enable PCA interrupt.
Bit 0: ESF, Enable System Flag interrupt.
0: Disable the interrupt when the group of {KBIF, BOF1, BOF0, WDTF} in PCON1, {STAF, STOF} in AUXR1 or TI0
in S0CON is set
1: Enable the interrupt of the flags of {KBIF, BOF1, BOF0, WDTF} in PCON1, {STAF, STOF} in AUXR1 or TI0 in
S0CON when the associated system flag interrupt is enabled in SFIE.
