Description
P2[8] — General purpose digital input/output pin.
TD2 — CAN2 transmitter output.
TXD2 — Transmitter output for UART2.
TRACEPKT3 — Trace packet, bit 3.^[17]
LCDVD[2]/LCDVD[6] — LCD data.^[17]
P2[9] — General purpose digital input/output pin.
USB_CONNECT1 — USB1 SoftConnect control. Signal used to switch
an external 1.5 kΩ resistor under the software control. Used with the
SoftConnect USB feature.
RXD2 — Receiver input for UART2.
EXTIN0 — External Trigger Input.^[17]
LCDVD[3]/LCDVD[7] — LCD data.^[17]
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.
EINT0 — External interrupt 0 input.
P2[11] — General purpose digital input/output pin.
EINT1 — External interrupt 1 input.^[18]
LCDCLKIN — LCD clock.^[18]
MCIDAT1 — Data line 1 for SD/MMC interface.
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] — General purpose digital input/output pin.
EINT2 — External interrupt 2 input.^[18]
LCDVD[4]/LCDVD[3]/LCDVD[8]/LCDVD[18] — LCD data.^[18]
MCIDAT2 — Data line 2 for SD/MMC interface.
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] — General purpose digital input/output pin.
EINT3 — External interrupt 3 input.^[18]
LCDVD[5]/LCDVD[9]/LCDVD[19] — LCD data.^[18]
MCIDAT3 — Data line 3 for SD/MMC interface.
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.
P2[14] — General purpose digital input/output pin.
CS2 — LOW active Chip Select 2 signal.
CAP2[0] — Capture input for Timer 2, channel 0.
SDA1 — I²C1 data input/output (this is not an open-drain pin).
P2[15] — General purpose digital input/output pin.
CS3 — LOW active Chip Select 3 signal.
CAP2[1] — Capture input for Timer 2, channel 1.
SCL1 — I²C1 clock input/output (this is not an open-drain pin).
