Description

configure vddsdio register

Fields

SDIO_TIMER_TARGET

timer count to apply reg_sdio_dcap after sdio power on
SDIO_DTHDRV

Tieh = 1 mode drive ability. Initially set to 0 to limit charge current set to 3 after several us.
SDIO_DCAP

ability to prevent LDO from overshoot
SDIO_INITI

add resistor from ldo output to ground. 0: no res 1: 6k 2: 4k 3: 2k
SDIO_EN_INITI

0 to set init[1:0]=0
SDIO_DCURLIM

tune current limit threshold when tieh = 0. About 800mA/(8+d)
SDIO_MODECURLIM

select current limit mode
SDIO_ENCURLIM

enable current limit
SDIO_REG_PD_EN

power down SDIO_REG in sleep. Only active when reg_sdio_force = 0
SDIO_FORCE

1: use SW option to control SDIO_REG 0: use state machine
SDIO_TIEH

SW option for SDIO_TIEH. Only active when reg_sdio_force = 1
REG1P8_READY

read only register for REG1P8_READY
DREFL_SDIO

SW option for DREFL_SDIO. Only active when reg_sdio_force = 1
DREFM_SDIO

SW option for DREFM_SDIO. Only active when reg_sdio_force = 1
DREFH_SDIO

SW option for DREFH_SDIO. Only active when reg_sdio_force = 1
XPD_SDIO

SW option for XPD_VOOSDIO. Only active when reg_sdio_force = 1
