Description
Reserved
These are read-only bits and cannot be modified.
Reserved
These bits are always read as 0. The write value should
always be 0.
Write Data Buffer Enable
The write data buffer function can be used for an
external write cycle and a DMAC single address
transfer cycle.
The changed setting may not affect an external access
immediately after the change.
0: Write data buffer function not used
1: Write data buffer function used
WAIT Pin Enable
Selects enabling/disabling of wait input by the WAIT
pin.
0: Wait input by WAIT pin disabled
1: Wait input by WAIT pin enabled
For details, see section 11, I/O Ports.
DACK Control
Selects the timing of DMAC transfer acknowledge
signal assertion.
0: DACK signal is asserted at the Bφ falling edge
1: DACK signal is asserted at the Bφ rising edge
Reserved
This bit is always read as 0. The write value should
always be 0.
Reserved
These are read-only bits and cannot be modified.
WAIT pin can be used as I/O port
