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, see section 22, 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 is the bus master is accepted after the bus
mastership has been transferred to the CPU by the bus controller.
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.
6.4.6
When the I bit is set by an LDC, ANDC, ORC, or XORC instruction, a PC break interrupt
becomes valid two states after the end of the executing instruction. If a PC break interrupt is set
for the instruction following one of these instructions, since interrupts, including NMI, are
disabled for a 3-state period in the case of LDC, ANDC, ORC, and XOR, the next instruction is
always executed. For details, see section 5, Interrupt Controller.
