Description of bit 6 (DISEL) added.
When this bit is set to 1, a CPU interrupt request is generated
every time data transfer ends (the DTC clears the interrupt
source flag for the activation source). When this bit is cleared
to 0, a CPU interrupt request is generated only when the
specified number of data transfer ends (the DTC does not
clear the interrupt source flag for the activation source).
Data bus
,
Usable for scan operations of CIN7 to CIN0
DTC operates in high-speed mode even when the LSI is in
medium-speed mode
