The hold signal is used to transfer the bus privileges from the CPU to the external circuits. Inputting “L” to
the HOLD pin places the microcomputer in the hold state at the end of the current bus access. This status
is maintained and “L” is output from the HLDA pin as long as “L” is input to the HOLD pin. Table 1.9.6
shows the microcomputer status in the hold state.
Bus-using priorities are given to HOLD, DMAC, and CPU in order of decreasing precedence.
Table 1.9.7 shows the external bus status when the internal area is accessed.
