Type Description
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/
MCIDAT1/
I2STX_CLK
52^[6]
I/O P2[11] — General purpose digital input/output pin.
I
EINT1 — External interrupt 1 input.
O
MCIDAT1 — Data line for SD/MMC interface.
I/O I2STX_CLK — Transmit Clock. It is driven by the master and received by the slave.
Corresponds to the signal SCK in the I²S-bus specification.
P2[12]/EINT2/
MCIDAT2/
I2STX_WS
51^[6]
I/O P2[12] — General purpose digital input/output pin.
I
EINT2 — External interrupt 2 input.
O
MCIDAT2 — Data line for SD/MMC interface.
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 I²S-bus specification.
P2[13]/EINT3/
MCIDAT3/
I2STX_SDA
50^[6]
I/O P2[13] — General purpose digital input/output pin.
I
EINT3 — External interrupt 3 input.
O
MCIDAT3 — Data line for SD/MMC interface.
I/O I2STX_SDA — Transmit data. It is driven by the transmitter and read by the
receiver. Corresponds to the signal SD in the I²S-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]/ 27^[1]
PWM1[2]
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]/ 26^[1]
PWM1[3]
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.
P4[28]/MAT2[0]/ 82^[1]
TXD3
I/O P4[28] — General purpose digital input/output pin.
O
MAT2[0] — Match output for Timer 2, channel 0.
O
TXD3 — Transmitter output for UART3.
P4[29]/MAT2[1]/ 85^[1]
RXD3
I/O P4[29] — General purpose digital input/output pin.
O
MAT2[1] — Match output for Timer 2, channel 1.
I
RXD3 — Receiver input for UART3.
TDO
1^[1]
O
TDO — Test Data Out for JTAG interface.
TDI
2^[1]
I
TDI — Test Data In for JTAG interface.
TMS
3^[1]
I
TMS — Test Mode Select for JTAG interface.
TRST
4^[1]
I
TRST — Test Reset for JTAG interface.
TCK
5^[1]
I
TCK — Test Clock for JTAG interface. This clock must be slower than ¹â„₆ of the CPU
clock (CCLK) for the JTAG interface to operate.
