How to enter deep software standby?

Latest Updated:08/10/2012

Question:

I cannot enter deep software standby.

Answer:

Perform the following settings before entering deep software standby.
- Set both the voltage monitoring 1 circuit mode select bit (LVD1CR0.LVD1RI) and the voltage monitoring 2 circuit mode select bit (LVD2CR0.LVD2RI) to 0 (voltage monitoring 1 interrupt generated when Vdet1 is crossed, and voltage monitoring 2 interrupt generated when Vdet2 is crossed).
- Set the software standby bit (SBYCR.SSBY) to 1 and the deep software standby bit (DPSBYCR.DPSBY) to 1 (shifts to deep software standby mode after the WAIT instruction is executed).
- Set deep standby interrupt flag register y (DPSIFRy) to 00h.
