Warming Up At The Release Of Low Power Consumption Mode - Toshiba TXZ+ Series Reference Manual

1.3.3.2. Warming up at the release of Low Power Consumption mode

Warming up may be required because of stability of an internal oscillator at the time of mode transition.
When shifting from STOP1 mode to a NORMAL mode, an internal oscillation is chosen automatically and the
warming up timer is started. The Output of a system clock is started after warming up time progress.
For this reason, before executing the command which shifts to the STOP1 mode, set up warming up time by
[CGWUPHCR]<WUPT[15:4]>. For the setting method, refer to "1.2.4.1. The warming up timer for a high speed
oscillation".
The following table shows the necessary of a warming up setup at the time of each Operation mode transition.
