Standby Mode
The TMP1941AF exits the standby mode after the warm-up period timer expires.
INTDMA is accepted only in IDLE (Doze) mode.
If the interrupt request level is greater than the mask level, an interrupt signal which is programmed as level-
sensitive must be held active until interrupt processing begins. Otherwise, the interrupt will not be serviced
successfully.
If interrupts are disabled in the CPU, all interrupts other than those used for wake-up signaling must also be
disabled in the Interrupt Controller (INTC) before a standby mode is entered. Otherwise, any interrupt could
take the TMP1941AF out of the standby mode.
