EPA Mask Registers
Figures 7-3 and 7-4 illustrate the EPA mask registers, EPA_MASK and EPA_MASK1, for the
8XC196Lx microcontroller family.

Setting a bit enables the corresponding interrupt as a EPA
x
 interrupt source. The shared 
EPA
x
 interrupt is enabled by setting its interrupt enable bit in the interrupt mask register 
(INT_MASK.0 = 1).
Bits 2–5 and 14–15 are reserved on the 8XC196L
x
 device family. For compatibility with future 
devices, write zeros to these bits.
