__________
HOLD > DMAC > CPU
(7) Hold Signal
This signal is used to transfer control of the bus from the CPU or DMAC to an external circuit. When the
__________
input on HOLD pin is pulled low, the microcomputer is placed in a hold state after the bus access then in
__________
process finishes. The microcomputer remains in the hold state while the HOLD pin is held low, during
__________
which time the HLDA pin outputs a low-level signal.
Table 2.4.7 shows the microcomputer status in the hold state.
__________
Bus-using priorities are given to HOLD, DMAC, and CPU in order of decreasing precedence. However,
if the CPU is accessing an odd address in word units, the DMAC cannot gain control of the bus during two
separate accesses.
Figure 2.4.10. Bus-using Priorities
Note 1: When I/O port function is selected.
(8) BCLK Output
If the PM07 bit in the PM0 register is set to “0” (output enable), a clock with the same frequency as that
of the CPU clock is output as BCLK from the BCLK pin. Refer to “CPU clock and pheripheral clock”.
