Description
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.
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.
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 I
P2[12] — General purpose digital input/output pin.
EINT2 — External interrupt 2 input.
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 I
specification.
P2[13] — General purpose digital input/output pin.
EINT3 — External interrupt 3 input.
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 I
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 — I
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 — I
P2[16] — General purpose digital input/output pin.
CAS — LOW active SDRAM Column Address Strobe.
P2[17] — General purpose digital input/output pin.
RAS — LOW active SDRAM Row Address Strobe.
P2[18] — General purpose digital input/output pin.
CLKOUT0 — SDRAM clock 0.
P2[19] — General purpose digital input/output pin.
CLKOUT1 — SDRAM clock 1.
