8.4.4 Repeat Mode
Repeat mode is useful for cyclically transferring a bit pattern from a table to the programmable
timing pattern controller (TPC) in synchronization, for example, with ITU compare match. Repeat
mode can be selected for each channel independently.
One byte or word is transferred per request in repeat mode, as in I/O mode. A designated number
of these transfers are executed. One address is specified in the memory address register (MAR),
the other in the I/O address register (IOAR). At the end of the designated number of transfers,
MAR and ETCR are restored to their original values and operation continues. The direction of
transfer is determined automatically from the activation source. The transfer is from the address
specified in IOAR to the address specified in MAR if activated by an SCI receive-data-full
interrupt, and from the address specified in MAR to the address specified in IOAR otherwise.
Table 8-8 indicates the register functions in repeat mode.
