Half End Interrupt Enable
Specifies whether an interrupt request is generated to
the CPU when the number of transfers is decreased to
half of the TCR value (a read transfer cycle end) set
preceding the transfer. When the HIE bit is set to 1 and
the HE bit is set, an interrupt request is generated to
the CPU. To confirm the half end of the transfer,
execute a dummy read of the destination space and
issue the SYNCO instruction. Clear this bit to 0 while
reload mode is set. This bit is valid in CHCR0 to
CHCR3 and CHCR6 to CHCR9.
0: Disables the half end interrupt
1: Enables the half end interrupt
17 AM 0 R/W
Acknowledge
Mode
Selects whether DACK is output in data read cycle or in
data write cycle.
This bit is valid only in CHCR0 to CHCR3.
0: DACK output in read cycle
1: DACK output in write cycle
16 AL 0 R/W
Acknowledge
Level
Specifies whether the DACK signal output is high active
or low active.
This bit is valid only in CHCR0 to CHCR3.
0: Low-active output of DACK (
DACK
)
1: High-active output of DACK
