7.2.4 Bus Timing

8 /
0 .
B
Bus cycle for the internal memory is basically one BCLK cycle. When the PM12 bit in the PM1 register is
set to "1" (wait state), the bus cycles are two BCLK cycles.
Bus cycles for SFRs are basically two BCLK cycles. When the PM13 bit in the PM1 register is set to "1"
(2 wait states), the bus cycles are three BCLK cycles.
Basic bus cycle for an external space is 2ø (1ø+1ø) to read and to write. Bus cycle is selected by the
EWCRi register (i=0 to 3) from 12 types of separate bus settings and 7 types of multiplexed bus settings.
If the EWCRi04 to EWCRi00 bits are set to "00011
Figure 7.3 shows the EWCRi register. Figures 7.4 to 7.8 show bus timing in an external space.
