15.25.7.13 GPIO_PRT_CFG_OUT
Description:
Port output buffer configuration register
Address:
0x4031004C
Offset:
0x4C
Retention:
Retained
IsDeepSleep:
No
Comment:
Configures the output driver for each pin.
Note: when initializing IO's that are connected to a live bus (such as I2C), make sure the
peripheral and HSIOM (HSIOM_PRT_SELx) is properly configured before setting the IO drive
mode to avoid producing glitches on the bus.
Default:
0x0
