Note: When reprogramming the internal flash memory in the CPU reprogramming mode, select the bus cycle = 3
φ.
q Number of bus cycles
Figure 17 shows the bus cycle waveform at access to the internal
area. Bit 7 of the processor mode register 1 (address 5F16) selects
the number of bus cycles for the internal ROM: 3
φ or 2φ. (This bit 7 is
the internal ROM bus cycle select bit.) The internal RAM, SFRs (in-
ternal peripheral devices’ control registers) are always accessed with
1 bus cycle = 2
φ. Figure 18 shows the bus cycle waveform at access
to the external area. The bus cycle select bits 0, 1 (See the note in
___
Figure 18.) select the number of the bus cycles for each CSi area
from 8 types of numbers.
