6.2.1.3.1 P2 (A0h) : Port 2 Register
6.2.1.3.2 P2TYPE (D6h) : Port 2 Type Control Register
6.2.1.3.3 P2SEL (E6h) : Port 2 Pull-up Control Register
MiDAS1.1 Family
is configured to push-pull output type.
0 = Push-pull output type.
1 = Open-drain output.
0 = Pull-up ON. The bit is configured to pull-up ON.
1 = Pull-up OFF. The bit is configured to pull-up OFF.
This register functions as a general purpose I/O port. The initial value of P2 is *1111111.
This register configures the P2 output type to the push-pull or open-drain. The initial P2 output type
This register is enables/disabled the internal pull-up in P2.
