Section 5 Interrupt Controller
5.2
Note: The H8S/2635 Group is not equipped with a DTC, a PC brake controller, or an HCAN1.
5.2.1
SYSCR is an 8-bit readable/writable register that selects the interrupt control mode, and the
detected edge for NMI.
Only bits 5 to 3 are described here; for details of the other bits, see section 3.2.2, System Control
Register (SYSCR).
SYSCR is initialized to H'01 by a reset and in hardware standby mode. SYSCR is not initialized in
software standby mode.
Bits 5 and 4—Interrupt Control Mode 1 and 0 (INTM1, INTM0): These bits select one of two
interrupt control modes for the interrupt controller.
0
1
Bit 3—NMI Edge Select (NMIEG): Selects the input edge for the NMI pin.
