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
1: Falling edge sensing
for the first transfer after transfer is enabled.)
