4.3.2.4
Setting the PTxCLR bit, clears the corresponding bit of the port data register, PTxD. Clearing a PTxCLR
bit has no effect on the PTxD register.Writes to the PTxCLR only cause the PTxD to change. Subsequent
writes to PTxD, PTxSET, or PTxTOG have their own effect in changing the PTxD register.
4.3.2.5
Setting a PTxTOG bit inverts the corresponding bit of the port data register, PTxD. Clearing a PTxTOG
bit has no effect on the port data register. Writes to the PTxTOG only cause the PTxD to change.
Subsequent writes to PTxD, PTxSET, or PTxCLR have their own effect in changing the PTxD register.
