Description

SDMMC Status Register 1

Fields

SD_VDD1_ON

Switch on VDD1/VDD bus power for SD card/eMMC
SD_VDD1_SEL

Select VDD1 voltage level for SD card/eMMC

5 (Val_0x5): 1.8V

6 (Val_0x6): 3.0V

7 (Val_0x7): 3.3V
UHS1_SWVOLT_EN

Switch voltage from 3.3 V to 1.8 V for UHS-I This bit is a command to external voltage regulator to switch voltage from 3.3V to 1.8V.

0 (Val_0x0): 3.3-V SD card signaling

1 (Val_0x1): 1.8-V SD card signaling
UHS1_DRV_STH

UHS-I driver strength select Host controller indicates output driver strength in 1.8-V signaling. In 3.3-V signaling, this output is not effective.

0 (Val_0x0): Driver Type B (Default)

1 (Val_0x1): Driver Type A

2 (Val_0x2): Driver Type C

3 (Val_0x3): Driver Type D
