Port P1 (P13 to P11)
Port P1 is a 3-bit input/output port that can be set to input or output for each bit individually. P13 to P11 are
(P10 is not I/O port for this product, because it is used only as the external reset input.)
P13.P12,P11 contains a programmable pull-up resistor on the VDD side. This pull-up resistor can be used
