Enable Bit = 1 enables the interrupt .

Enable Bit = 0 disables it .

EA (IE.7): disables all interrupts. if EA = 0,no interrupt will be acknowledged. if EA = 1, each

interrupt source is individually enabled or disabled by setting or clearing its enable bit.

EPCA_LVD (IE.6): Interrupt controller of Programmable Counter Array (PCA) and Low-Voltage Detector

0 : Disable theinterrupt of Programmable Counter Array (PCA) and Low-Voltage Detector

1 : enable theinterrupt of Programmable Counter Array (PCA) and Low-Voltage Detector

PPCA_LVDH, PPCA_LVD : Programmable Counter Array (PCA) and Low voltage detector interrupt priority control bits.

if PPCA_LVDH=0 and PPCA_LVD=0, Programmable Counter Array (PCA) and Low voltage detector

interrupt are assigned lowest priority(priority 0).

if PPCA_LVDH=0 and PPCA_LVD=1, Programmable Counter Array (PCA) and Low voltage detector

interrupt are assigned lowest priority(priority 1).

if PPCA_LVDH=1 and PPCA_LVD=0, Programmable Counter Array (PCA) and Low voltage detector

interrupt are assigned lowest priority(priority 2).

if PPCA_LVDH=1 and PPCA_LVD=1, Programmable Counter Array (PCA) and Low voltage detector

interrupt are assigned lowest priority(priority 3).
