6.4
6.4.1
PBC operation can be disabled or enabled using the module stop control register. The initial
setting is for PBC operation to be halted. Register access is enabled by clearing module stop
mode. For details, refer to section 24, Power-Down Modes.
6.4.2
The PC break interrupt is shared by channels A and B. The channel from which the request was
issued must be determined by the interrupt handler.
6.4.3
The CMFA and CMFB flags are not automatically cleared to 0, so 0 must be written to CMFA or
CMFB after first reading the flag while it is set to 1. If the flag is left set to 1, another interrupt
will be requested after interrupt handling ends.
6.4.4
A PC break interrupt generated when the DTC and DMAC* is the bus master is accepted after the
bus has been transferred to the CPU by the bus controller.
Note: * Supported only by the H8S/2239 Group.
6.4.5
Even if the instruction at the address following a BSR, JSR, JMP, TRAPA, RTE, or RTS
instruction is fetched, it is not executed, and so a PC break interrupt is not generated by the
instruction fetch at the next address.
Rn as its addressing mode, and that instruction is located in on-chip ROM or RAM, the
instruction will be one state later than in normal operation.
