RX23W Group 8. Voltage Detection Circuit (LVDAb)

8.3 VCC Input Voltage Monitor

8.3.1 Monitoring Vdet0

Monitoring Vdet0 is not possible.

8.3.2 Monitoring Vdet1

After making the following settings, the LVD1SR.LVD1MON flag can be used to monitor the results of comparison by

voltage monitor 1.

(1) Specify the detection voltage by setting the LVDLVLR.LVD1LVL[3:0] bits (voltage detection 1 level select).

(2) Set the LVCMPCR.LVD1E bit to 1 (voltage detection 1 circuit enabled).

(3) After waiting for td(E-A), set the LVD1CR0.LVD1CMPE bit to 1 (voltage monitoring 1 circuit comparison results

output enabled).
