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.
