I/O
purpose I/O port, which can be configured as Input,
Output, Quasi-bidirectional and Open-drain mode.
I/O
Port 3 supports multi-function pins, including PWM0 ~
PWM3, nCS, ALE, ICE_CLK, ICE_DAT, SCL1, SDA1,
T2EX and T3EX.
I/O _{The PWM0 ~ PWM3 pins are for PWM function.}
The nCS and ALE pins are for EBI function.
I/O _{The ICE_CLK and ICE_DAT pins are for Serial Wire}
Debug Interface.
I/O _{The SDA1 and SCL1 pins are for I}2_{C1 function and both}
of them are open-drain.
I/O _{The T2EX and T3EX pins are for external capture/reset}
trigger input of Timer2/3.
I/O
Note 1: I/O type description. I: Input, O: Output, I/O: Quasi-bidirectional, D: Open-drain, P: Power pins, ST: Schmitt trigger.
Note 2: The PWM0 ~ PWM3, RXD, TXD, RXD1, TXD1, SCL1, SDA1 and CKO can be assigned to different pins. However,
a pin function can only be assigned to a pin at the same time, i.e. software cannot assign RXD to P0.3 and P3.0 at the same
time.
