The CLK
In memory expansion and microprocessor modes, a clock having the same frequency as the CPU clock
can be output from the BCLK pin as BCLK.
Table 8.4 lists CLK
expansion and microprocessor modes.
Normal operation mode, wait mode and stop mode are provided as the power consumption control.
All mode states, except wait mode and stop mode, are called normal operation mode in this document.
Figure 8.14 shows a block diagram of status transition in wait mode and stop mode. Figure 8.15 shows a
block diagram of status transition in all modes.
