DMATCR is an 8-bit readable/writable register that controls enabling or disabling of DMAC
transfer end pin output. A port can be set for output automatically, and a transfer end signal
output, by setting the appropriate bit.
DMATCR is initialized to H'00 by a reset, and in hardware standby mode.
Bits 7 and 6—Reserved: Read-only bits, always read as 0.
Bit 5—Transfer End Enable 1 (TEE1): Enables or disables transfer end pin 1 (TEND1) output.
Bit 5
TEE1
Description
0 TEND1 pin output disabled (Initial value)
1 TEND1 pin output enabled
Bit 4—Transfer End Enable 0 (TEE0): Enables or disables transfer end pin 0 (TEND0) output.
Bit 4
TEE0
Description
0 TEND0 pin output disabled (Initial value)
1 TEND0 pin output enabled
The TEND pins are assigned only to channel B in short address mode.
The transfer end signal indicates the transfer cycle in which the transfer counter reached 0,
regardless of the transfer source. An exception is block transfer mode, in which the transfer end
signal indicates the transfer cycle in which the block counter reached 0.
Bits 3 to 0—Reserved: Read-only bits, always read as 0.
