Note: When reprogramming the internal flash memory in the CPU reprogramming mode, select the bus cycle = 3

q Number of bus cycles
Figure 9 shows the bus cycle waveform at access to the internal
area. Bit 7 of the processor mode register 1 (address 5F16), which is
shown in Figure 10, 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 (internal peripheral devices’ control regis-
ters) are always accessed with 1 bus cycle = 2
φ.
