When a multichannel selection mode is used, an interrupt request can be sent to the CPU at the end of every 16-channel block (at the boundary between partitions and at the end of the frame). In the receive multichannel selection mode, a receive interrupt (RINT) request is generated at the end of each block transfer if RINTM = 01b. In any of the transmit multichannel selection modes, a transmit interrupt (XINT) request is generated at the end of each block transfer if XINTM = 01b. When RINTM/XINTM = 01b, no interrupt is generated unless a multichannel selection mode is on.
These interrupt pulses are active high and last for two CPU clock cycles.
This type of interrupt is especially helpful if you are using the two-partition mode (described in Section 34.6.4) and you want to know when you can assign a different block of channels to partition A or B.
