Table 6-53. SLEEP_KEEP_LDO_ON_REG
Address Offset 0x41
Physical Address Instance
Description When corresponding control bit=0 in EN1/2_ LDO_ASS register (default setting): Configuration Register
keeping the full load capability of LDO regulator (ACTIVE mode) during the SLEEP state of the device.
When control bit=1, LDO regulator full load capability (ACTIVE mode) is maintained during device
SLEEP state.
When control bit=0, the LDO regulator is set or stay in low power mode during device SLEEP state(but
then supply state can be overwritten programming ST[1:0]). Control bit value has no effect if the LDO
regulator is off.
When corresponding control bit=1 in EN1/2_ LDO_ASS register: Configuration Register setting the LDO
regulator state driven by SCLSR_EN1/2 signal low level (when SCLSR_EN1/2 is high the regulator is
on, full power):
- The regulator is set off if its corresponding Control bit = 0 in SLEEP_KEEP_LDO_ON register (default)
- The regulator is set in low power mode if its corresponding control bit = 1 in SLEEP_KEEP_LDO_ON
