6.1.3 Interrupt Details
Details of the interrupts described in Table 6-1 are:
COMMRX
ARM Communication Channel Receive. When high,
COMMRX indicates that the communications channel
receive buffer contains data waiting to be read by the ARM
Core. Refer to the ARM Technical Reference Manual.
COMMTX
ARM Communication Channel Transmit. When high
COMMTX indicates that the communications channel
transmit buffer is empty. Refer to the ARM Technical
Reference Manual.
