Bits 7:0 – PINCTRLUPD[7:0] Multi-Pin Control Update Mask
This bit field controls the copy of the Multi-Pin Configuration (PORTx.PINCONFIG) register content to the individual Pin n Control (PORTx.PINnCTRL) registers without using an individual 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 copy
the PORTx.PINCONFIG register content to the corresponding PORTx.PINnCTRL
register.
Reading this bit field will always return zero.
