Table 8.9 lists external bus states when the internal space is accessed.
The bus clock can be output from the BCLK pin in memory expansion mode and microprocessor mode. To
output the bus clock, set the PM07 bit in the PM0 register to 0 (BCLK output) and bits CM01 and CM00 in the
CM0 register to 00b (I/O port P5_3). No BCLK is output in single-chip mode.
Refer to 9. Clock Generation Circuits for details.
