Bits 7:0 – PINCTRLCLR[7:0] Multi-Pin Control Clear Mask

This bit field controls the clearing of bits in the individual Pin n Control (PORTx.PINnCTRL) registers without using an individual read-modify-write operation for each register.

Writing a ‘0’ to bit n in this bit field has no effect.

Writing a ‘1’ to bit n in this bit field will clear the individual bits in the PORTx.PINnCTRL register, according to the bits set to ‘1’ in the Multi-Pin Configuration (PORTx.PINCONFIG) register.

Reading this bit field will always return zero.
