Pin Function
1.7.5 External Reset Pin (RST)
A logic 0 on the RST pin forces the MCU to a known start-up state. RST is bidirectional, allowing a reset
of the entire system. It is driven low when any internal reset source is asserted. A schmitt-trigger and a
spike filter is associated with this pin so that the device is more robust to EMC noise.This pin also contains
an internal pullup resistor.
1.7.6 External Interrupt Pin (IRQ)
IRQ is an asynchronous external interrupt pin. This pin contains an internal pullup resistor.
1.7.7 External Filter Capacitor Pin (CGMXFC)
CGMXFC is an external filter connection for the on-chip PLL.
1.7.8 Port A Input/Output (I/O) Pins (PTA7–PTA0)
PTA7–PTA0 are special function, bidirectional ports pins. These pins are shared with KBI module.
1.7.9 Port B Input/Output (I/O) Pins (PTB7–PTB0)
PTB7–PTB0 are special function, bidirectional ports pins. These pins can be programmable as
open-drain output with high current sourcing capability and has built-in programmable pull up resistor.
1.7.10 Port C Input/Output (I/O) Pins (PTC3–PTC0)
PTC0–PTC3 are bidirectional ports pins. PTC0–PTC2 are shared with TIMER channel 0, channel 1 and
TCLK1 pins respectively.
1.7.11 Port D Input/Output (I/O) Pins (PTD7–PTD0)
PTD7–PTD0 are bidirectional ports pins. Pullup option are associated with PTD2, 3 and 7. The option is
default enabled after reset.
1.7.12 Port E Input/Output (I/O) Pins (PTE7–PTE2)
PTE7–PTE2 are special function, bidirectional ports pins. PTE2–PTE3 are shared with USB 2.0 FS
module. PTE2 is shared with PS2 clock module. PTE4–PTE7 are shared with SPI module.
