Software Interrupts:
When set any bit of those registers indicates software interrupt
is on.
RXPCOM Valid:
When set this bit indicates a non-null RX_PCOM has been
received.
Accessing the high byte of the RX_PCOM register clears this
bit.
TXPCOM Ready:
When set this bit indicates a non-null TX_PCOM has been
loaded into the TX_PCOM register.
