(1) Version A: If device remains in reset greater than 100ms due
to V1 undervoltage, device switches to sleep mode to minimise
current consumption. Wake-up configuration active.

(2) Version C: In V1 undervoltage condition, device remains in
permanent reset state until V1 returns to nominal conditions. V1
protected by overcurrent and over temperature functions.

(3) Version D: In V1 undervoltage condition, device remains in
RX
permanent reset state until V1 returns to nominal conditions. V1
protected by overcurrent and over temperature functions.
Change of undervoltage reset threshold. Refer to electrical pa-
rameter table, V1 PIn 5V.
