4.3.3.2
Note:
The STOP mode is entered two cycles after the instruction that sets the STP bit to “1” and up to two instructions are
executed during the period between STOP mode release and a transition to interrupt processing. Therefore, place two
NOP instructions next to the instruction that set the STP bit to “1”.
When the CPU is operating with a high-speed clock and the STP bit of SBYCON is set to “1” with the stop code
acceptor enabled, the STOP mode is entered and high-speed oscillation and low-speed oscillation stop.
When the NMI interrupt request or the interrupt-enabled (the interrupt enable flag is “1”) P00 to P07 interrupt request
is issued, the STP bit is set to “0” and the low-speed and high-speed oscillation restart.
When an interrupt request is issued, the STOP mode is released after the elapse of the high-speed oscillation start time
(TXTH/TRC) and the high-speed clock (OSCLK) oscillation stabilization time (8192-pulse count), the mode is
returned to the program run mode, and the high-speed clocks (OSCLK and HSCLK) restart supply to the peripheral
circuits.
The low-speed clock (LSCLK) restarts supply to the peripheral circuits after the elapse of the low-speed oscillation
start time (TXTL) and low-speed clock (LSCLK) oscillation settling time (8192 count).
For the high-speed oscillation start time (TXTH) and low-speed oscillation start time (TXTL), see the “Electrical
Characteristics” Section in Appendix C.
Figure 4-4 shows the operation waveforms in STOP mode when CPU operates with the high-speed clock.
