Write
The Channel
x
Interrupt Condition register sets which conditions cause
interrupts to be generated by the modules Bits00 and 01 are used for transmit
channels and bits 02 through 06 are used for receive channels (see
Channel x
Interrupt Condition Register
on page 4-17 in
Chapter 4: Receive/ Monitor Mode
).
Read/Write
The Channel
x
Status register indicates the operational status of the channel.
Use this register to poll the status of the channel or it can be used with
interrupts. When used in conjunction with interrupts, the register indicates the
condition(s) which caused the interrupt. A logic 1 indicates an active bit. You
must reset the status bits. Only the two least significant bits are used for
transmit channels and only bits 02 through 06 are used for receive channels.

Channel x Status Register
