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
output enabled).
8.3.3

Monitoring Vdet2

After making the following settings, the LVD2SR.LVD2MON flag can be used to monitor the results of comparison by
voltage monitor 2.
(1) Specify the detection voltage by setting the LVDLVLR.LVD2LVL[1:0] bits (voltage detection 2 level select).
(2) Set the LVCMPCR.LVD2E bit to 1 (voltage detection 2 circuit enabled).
(3) After waiting for Td
output enabled).
