rc_w1
Bits 31:4 Reserved, must be kept at reset value.
Bit 3 BR3: Port PH3 reset output data bit [3] in GPIOH_ODR
This bit is read clear-write 1. A read to this bit returns the value 0.
0: No action on the corresponding GPIOH_ODR.OD3
1: Resets the corresponding GPIOH_ODR.OD3.
Bits 2:0 Reserved, must be kept at reset value.
