AIPOFF
R/W
0h
Override on AIPOFF input of SRAM LDO.
0x0 = No_Override : AIPOFF signal is not overriden
0x1 = Override : AIPOFF signal is overriden to '1'. Corresponding
SRAM LDO is disabled and in HZ mode.
7
ENFUNC5
R/W
0h
ENFUNC5 input of SRAM LDO.
0x0 = One_step : Active to retention is a one step transfer
0x1 = Two_step : Active to retention is a two steps transfer
6
ENFUNC4
R/W
0h
ENFUNC4 input of SRAM LDO.
0x0 = Ext_clock : One external clock is supplied
0x1 = No_ext_clock : No external clock is supplied
5
ENFUNC3_EXPORT
R/W
0h
ENFUNC3 input of SRAM LDO.
After PowerOn reset and Efuse sensing, this bitfield is automatically
loaded with an Efuse value from control module.
Bitfield remains writable after this.
0x0 = Sub_regul_disabled : Sub regulation is disabled
0x1 = Sub_regul_enabled : Sub regulation is enabled
4
ENFUNC2_EXPORT
R/W
0h
ENFUNC2 input of SRAM LDO.
After PowerOn reset and Efuse sensing, this bitfield is automatically
loaded with an Efuse value from control module.
Bitfield remains writable after this.
0x0 = Ext_cap : External cap is used
0x1 = No_ext_cap : External cap is not used
3
ENFUNC1_EXPORT
R/W
0h
ENFUNC1 input of SRAM LDO.
After PowerOn reset and Efuse sensing, this bitfield is automatically
loaded with an Efuse value from control module.
Bitfield remains writable after this.
0x0 = Short_prot_disabled : Short circuit protection is disabled
0x1 = Short_prot_enabled : Short circuit protection is enabled
