PIN CONFIGURATION
A “CMOS pin” can be used as Input or Output mode. To use these pins as output mode, S/W needs to set
the corresponding output enable control bit “Pxxoe” to 1. Otherwise, the “Pxxoe” should clear to 0. In Output
mode, these pins can sink and drive at least 4mA current.
A “5V open drain pin” means it can sink at least 4mA current but no drive current to VDD. It can be used as
input or output function and needs an external pull up resistor.
A “8051 standard pin” is a pseudo open drain pin. It can sink at least 4mA current when output low level, and
drive at least 4mA current for 160nS when output transit from low to high, then keep drive 100uA to maintain
the pin at a high level. It can be used as input or output function. It needs an external pull up resistor when
driving heavy load device.
