23.4.20 INTPND12 Register (offset = B0h) [reset = 0h]
INTPND12 is shown in Figure 23-38 and described in Table 23-33.
These registers hold the IntPnd bits of the implemented message objects. By reading out these bits, the
CPU can check for pending interrupts in the message objects. The IntPnd bit of a specific message object
can be set/reset by the CPU via the IF1/IF2 interface register sets, or by the message handler after a
reception or a successful transmission.
