Description
Block Transfer Error Flag
Flag that indicates the occurrence of an error during
block transfer. If an NMI interrupt is generated
during block transfer, the EXDMAC immediately
terminates the EXDMA operation and sets this bit to
1. The address registers indicate the next transfer
addresses, but the data for which transfer has been
performed within the block size is lost.
0: No block transfer error
[Clearing condition]
Writing 0 to BEF after reading BEF = 1
1: Block transfer error
[Setting condition]
NMI interrupt during block transfer
EDRAK Pin Output Enable
Enables output from the EDREQ
acknowledge/transfer processing start (EDRAK) pin.
0: EDRAK pin output disabled
1: EDRAK pin output enabled
ETEND Pin Output Enable
Enables output from the EXDMA transfer end
(ETEND) pin.
0: ETEND pin output disabled
1: ETEND pin output enabled
EDREQ Select
Specifies low level sensing or falling edge sensing
as the sampling method for the EDREQ pin used in
external request mode.
0: Low level sensing (Low level sensing is used for
1: Falling edge sensing
the first transfer after transfer is enabled.)
