Name

Base

Default

GPIO_Cntr

2-wire serial

00h

Offset: 17h-7

GPIO Control Register

This is an extended register and needs to be enabled by writing 111b to Reg. 1Ch first.

This register is reset at a VDD27-POR or XRES input.

00000

R/W

Sets the LDO output voltage in register control mode (default voltage of the

regulator is selected by boot ROM

0x00-0x0F: 1.2V+VSEL*50mV

→ (1.2V - 1.95V)

0x10-0x1F: 2.0V + (VSEL-0x10)*100mV

→ (2.0V-3.5V)
