On-Chip Peripheral Module Request Mode: In this mode a transfer is performed at the transfer
request signal (interrupt request signal) of an on-chip peripheral module. As indicated in table
10.3, there are ten transfer request signals: five from the multifunction timer pulse unit (MTU),
which are compare match or input capture interrupts; the receive data full interrupts (RXI) and
transmit data empty interrupts (TXI) of the two serial communication interfaces (SCI); and the
A/D conversion end interrupt (ADI1) of the A/D converter. When DMA transfers are enabled (DE
= 1, DME = 1, TE = 0, NMIF = 0, AE = 0), a transfer is performed upon the input of a transfer
request signal.
The transfer request source need not be the data transfer source or transfer destination. However,
when the transfer request is set by RXI (transfer request because SCI’s receive data is full), the
transfer source must be the SCI’s receive data register (RDR). When the transfer request is set by
TXI (transfer request because SCI’s transmit data is empty), the transfer destination must be the
SCI’s transmit data register (TDR). Also, if the transfer request is set to the A/D converter, the
data transfer destination must be the A/D converter register.
