This output can be used as the channel A transmitter 1X-clock or 16X-clock output or the
channel A receiver 1X-clock output.
2.15.4 OP3
This output can function as the open-drain active-low counter-ready output, the open-drain
timer output, the channel B transmitter 1X-clock output, or the channel B receiver 1X-clock
output.
2.15.5 OP4
This output can serve as the channel A open-drain active-low receiver-ready or buffer-full
interrupt outputs (RxRDYA/FFULLA) by appropriately programming bit 6 of mode
register 1A.
2.15.6 OP5
This output can be used as the channel B open-drain active-low receiver-ready or buffer-full
interrupt outputs (RxRDYB/FFULLB) by appropriately programming bit 6 of mode
register 1B.
2.15.7 OP6
This output can function as the channel A open-drain active-low transmitter-ready interrupt
output (TxRDYA).
