Clock/Standby Control
○: Starts the processing at the address next to the standby instruction (without executing the interrupt handling)
after the standby mode is released.
×: Cannot be used for releasing the standby mode
: Starts the interrupt handling after the standby mode is released. (The LSI is initialized by the reset.)

Standby mode
Release by an interrupt request
Release by the reset
mask level, or by the reset. The standby release source that can be used is determined by a combination of the
standby mode and the state of the interrupt mask register <IM15:8> assigned to the status register in the system
control coprocessor (CPO) of the TX19A / H1 processor core. Details are shown in Table 5.6.
state. If the interrupt level specified before the system enters the standby mode is equal to or higher than the
value of the interrupt mask register, an interrupt handling operation is executed by the trigger after the standby
is released, and the processing is started at the instruction next to the standby shift instruction (WAIT
instruction). If the interrupt request level is lower than the value of the interrupt mask register, the processing
is started with the instruction next to the standby shift instruction (WAIT instruction) without executing an
interrupt handling operation. (The interrupt request flag is maintained at "1.")
irrespectively of the mask register value.
Note that releasing of the STOP mode requires sufficient reset time to allow the oscillator operation to become
stable.

The standby state can be released by an interrupt request when the interrupt level is higher than the interrupt
Operations of releasing the standby state using an interrupt request vary depending on the interrupt enabled
For a non-maskable interrupt, an interrupt handling is executed after the standby state is released
Any standby state can be released by the reset.
