Bit 6—Enable of EXMSTP Output to P76 (P76STPOE): Selects whether or not the EXMSTP
module stop signal to external modules (bit 0 in MSTPCRB) is output to P76.
Bit 6
P76STPOE
Description
0
EXMSTP is not output to P76
(Initial value)
1
EXMSTP is output to P76
Bit 5—Enable of
EXMS Output to P75 (P75MSOE): Selects whether or not the EXMS module
stop signal to external modules (corresponding to addresses H'FFFF40 to H'FFFF5F) is output to
P75.
Bit 5
P75MSOE
Description
0
EXMS is not output to P75
(Initial value)
1
EXMS is output to P75
Bit 4—Enable of
EXDTCE Output to P74 (P74DTCOE): Selects whether or not the EXDTCE
signal, indicating that DTC transfer corresponding to EXIRQ0 to EXIRQF input is in progress, is
output to P74. This signal is used, for example, when the DTC in the chip has been activated by
an interrupt (EXIRQ0 to EXIRQF) from an external module, and the interrupt request is to be
cleared automatically on the external module side by DTC transfer.
Bit 4
P74DTCOE
Description
0
EXDTCE is not output to P74
(Initial value)
1
EXDTCE is output to P74
Bits 3 to 0—Reserved: These bits will return an undefined value if read, and should only be
written with 0.
