97 / 145 page  6.5.8 LDOx PWRCTRL control register (LDOx_PWRCTRL_CR) (x = 1 to 8) Table 61. LDOx_PWRCTRL_CR 7 6 5 4 3 2 1 0 PWRCTRL_DLY_H[1:0] PWRCTRL_DLY_L[1:0] PWRCTRL_SEL[1:0] PWRCTRL_RST PWRCTRL_EN R/W R/W R/W R/W R/W R/W R/W R/W • Address: 0x4E/0x51/0x54/0x57/0x5A/0x5D/0x60/0x63 • Default: 0x00 • Description: LDO1 to LDO8 PWRCTRL control register. This register is initialized to the default value in the CHECK&LOAD state. The user can write to these registers to allocate a PWRCTRL signal for controlling the LDOx (see Section 5.4.6). [7:6] PWRCTRL_DLY_H[1:0]: LDOx control/reset source shift delay from low to High level 00: no delay 01: 1.5 ms delay 10: 3 ms delay 11: 6 ms delay [5:4] PWRCTRL_DLY_L[1:0]: LDOx control/reset source shift delay from high to Low level 00: no delay 01: 1.5 ms delay 10: 3 ms delay 11: 6 ms delay [3:2] PWRCTRL_SEL[1:0]: LDOx control/reset PWRCTRL source selection. 00: No control source 01: PWRCTRL1 control source 10: PWRCTRL2 control source 11: PWRCTRL3 control source [1] PWRCTRL_RST: LDOx independent reset source enable 0: no effect 1: reset enable (when the selected PWRCTRL source is active, LDOx is disabled and LDOx control registers are reset to the default value. When the selected PWRCTRL source is inactive, LDOx operates according to LDOx_MAIN_CR. See Table 27). [0] PWRCTRL_EN: LDOx control source enable 0: disable (LDOx operates according to LDOx_MAIN_CR) 1: enable (LDOx operates according to LDOx_MAIN_CR or LDOx_ALT_CR depending on the PWRCTRL selected source. See Table 27). STPMIC25 Register descriptions DS14278 - Rev 3 page 97/145 |
