23.4.19 INTPND_X Register (offset = ACh) [reset = 0h]
INTPND_X is shown in
and described in
.
With the interrupt pending X register, the CPU can detect if one or more bits in the different interrupt
pending registers are set. Each bit of this register represents a group of eight message objects. If at least
one of the IntPnd bits of these message objects are set, the corresponding bit in the interrupt pending X
register will be set. Example 2. Bit 0 of the interrupt pending X register represents byte 0 of the interrupt
pending 1 register. If one or more bits in this byte are set, bit 0 of the interrupt pending X register will be
set.
