P2[9]/
USB_CONNECT/
RXD2/EXTIN0
64
[1]
I/O P2[9] — General purpose digital input/output pin.
O USB_CONNECT — Signal used to switch an external 1.5 k resistor under
software control. Used with the SoftConnect USB feature.
I RXD2 — Receiver input for UART2.
I EXTIN0 — External Trigger Input.
P2[10]/EINT0
53
[6]
I/O P2[10] — General purpose digital input/output pin.
Note: LOW on this pin while RESET
is LOW forces on-chip bootloader to take
over control of the part after a reset.
I EINT0
— External interrupt 0 input.
P2[11]/EINT1
/
I2STX_CLK
52
[6]
I/O P2[11] — General purpose digital input/output pin.
I EINT1
— External interrupt 1 input.
I/O I2STX_CLK — Transmit Clock. It is driven by the master and received by the
slave. Corresponds to the signal SCK in the I
2
S-bus specification.
P2[12]/EINT2
/
I2STX_WS
51
[6]
I/O P2[12] — General purpose digital input/output pin.
I EINT2
— External interrupt 2 input.
I/O I2STX_WS — Transmit Word Select. It is driven by the master and received by
the slave. Corresponds to the signal WS in the I
2
S-bus specification.
P2[13]/EINT3
/
I2STX_SDA
50
[6]
I/O P2[13] — General purpose digital input/output pin.
I EINT3
— External interrupt 3 input.
I/O I2STX_SDA — Transmit data. It is driven by the transmitter and read by the
receiver. Corresponds to the signal SD in the I
2
S-bus specification.
P3[0] to P3[31] I/O Port 3: Port 3 is a 32-bit I/O port with individual direction controls for each bit. The
operation of port 3 pins depends upon the pin function selected via the pin
connect block. Pins 0 through 24, and 27 through 31 of this port are not available.
P3[25]/MAT0[0]/
PWM1[2]
27
[1]
I/O P3[25] — General purpose digital input/output pin.
O MAT0[0] — Match output for Timer 0, channel 0.
O PWM1[2] — Pulse Width Modulator 1, output 2.
P3[26]/MAT0[1]/
PWM1[3]
26
[1]
I/O P3[26] — General purpose digital input/output pin.
O MAT0[1] — Match output for Timer 0, channel 1.
O PWM1[3] — Pulse Width Modulator 1, output 3.
P4[0] to P4[31] I/O Port 4: Port 4 is a 32-bit I/O port with individual direction controls for each bit. The
operation of port 4 pins depends upon the pin function selected via the pin
connect block. Pins 0 through 27, 30, and 31 of this port are not available.
