• Description: Low-speed USB micro-controller
• Manufacturer: MEGAWIN [Megawin Technology Co., Ltd]

When port 3 is used as the input mode, it provides the pin interrupt function while a falling edge occurs
at any pin of the port 3 and will set the P3 bit of the IRQ_ST SFR. The same event can release the stop
mode to enable the oscillator, and this interrupt also can release the halt mode if the P3 bit in the
RLH_EN SFR is set. Finally, an interrupt subroutine will be executed if setting the P3 bit in the IRQ_E
SFR.
Port 4
MPC2F35 only provide two pins (P4.0 and P4.1) on the port 4, and these pins also are I/O pins. The
structure is the same with Port

P3_CR: Configure P3.0 ~ P3.7 to be input or output individually. 0: input, 1: output
P3_MR: Configure the output mode of P3.0 ~ P3.7 with a 17k ohm pull-high resistor, CMOS
P4_BUF: Port 4 output buffer. When P4.n is configured as an output pin, it outputs the content
P4: Values on Port 4 pins while reading from Port 4.
P4_CR: Configure P4.0 and P4.1 to be input or output individually. 0: input, 1: output
P4_MR: Configure the output mode of P4.0 and P4.1 with a 17k ohm pull-high resistor,
