RH850 deepstop sampling problem(LPS)

When we use the LPS sampling function of the RH850/F1KM-S1, we define a number of analog input channels as a Group, and the external analog inputs are all high level pull-up key scanning, and we set a smaller sampling value as a range limit, but when the test enters into the DEEPSTOP, one of the keys wakes up right away, but the normal operation mode AD sampling value of this key is also right. What are the possible reasons for this problem?

Attached is the relevant reference code, Can you help us see what is the problem ?Thanks!
