17.5.13 Multi-Pin Control Update Mask

For faster configuration of the port module, the multi-pin configuration write enables the configuration of several pins of a port in a single cycle. Especially with large pin count devices, this function can significantly speed up PORT pin configuration operations.

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.
