stop mode. In stop mode, the content of the internal RAM is retained provided that Vcc remains above 2V.
Because the oscillation of BCLK, f
such as the A/D converter and watchdog timer do not function. However, timer A operates, provided that the event
counter mode is set to an external pulse, and UARTi (i = 0 to 3) functions provided an external clock is selected. Table
1.24 shows the status of the ports in stop mode.
Stop mode is cancelled by a hardware reset or interrupt. If an interrupt is to be used to cancel stop mode, that interrupt
must first be enabled and the interrupt priority of any interrupts not used to cancel stop mode should be set to "0". The
I flag must also be set prior to stopping for an interrupt to cancel it. When returning by an interrupt, that interrupt routine
is executed. If only a hardware reset or an NMI interrupt is used to cancel stop mode, change the priority level of all
interrupts to "0", then change to stop mode.
After coming out of stop mode, it is recommended that four "NOP" instructions be executed to clear the instruction
queue.
When changing from high-speed/medium speed mode to stop mode and at reset, the main clock division select bit 0
(bit 6 at 0006
before stop mode is retained.
