Description
DACK Signal Output Enable
Enables/disables the DACK signal output in single
address mode. This bit is ignored in dual address mode.
0: Enables DACK signal output
1: Disables DACK signal output
TEND Signal Output Enable
Enables/disables the TEND signal output.
0: Enables TEND signal output
1: Disables TEND signal output
Reserved
Initial value should not be changed.
DREQ Select
Selects whether a low level or the falling edge of the
DREQ signal used in external request mode is detected.
When a block transfer is performed in external request
mode, clear this bit to 0.
0: Low level detection
1: Falling edge detection (the first transfer after a
Next Request Delay
Selects the accepting timing of the next transfer request.
0: Starts accepting the next transfer request after
1: Starts accepting the next transfer request one cycle
Reserved
These bits are always read as 0 and cannot be
modified.
Active State
Indicates the operating state for the channel.
0: Waiting for a transfer request or a transfer disabled
1: Active state
Reserved
These bits are always read as 0 and cannot be
modified.
