Reserved
These bits are always read as 0. The write value
should always be 0.
DMA Overrun
Selects whether DREQ is detected by overrun 0 or by
overrun 1. This bit is valid only in level detection by
CHCR_0 to CHCR_3. This bit is reserved in CHCR_4
to CHCR_7; it is always read as 0 and the write value
should always be 0.
0: Detects DREQ by overrun 0
1: Detects DREQ by overrun 1
Transfer End Level
Specifies the TEND signal output is high active or low
active. This bit is valid only in CHCR_0 and CHCR_1.
This bit is reserved in CHCR_2 to CHCR_7; it is
always read as 0 and the write value should always be
0.
0: Low-active output from TEND
1: High-active output from TEND
Reserved
This bit is always read as 0. The write value should
always be 0.
