Description
P0[9] — General purpose digital input/output pin.
I2STX_SDA — Transmit data. It is driven by the transmitter and read by the
receiver. Corresponds to the signal SD in the I
MOSI1 — Master Out Slave In for SSP1.
MAT2[3] — Match output for Timer 2, channel 3.
P0[10] — General purpose digital input/output pin.
TXD2 — Transmitter output for UART2.
SDA2 — I
MAT3[0] — Match output for Timer 3, channel 0.
P0[11] — General purpose digital input/output pin.
RXD2 — Receiver input for UART2.
SCL2 — I
MAT3[1] — Match output for Timer 3, channel 1.
P0[12] — General purpose digital input/output pin.
USB_PPWR2 — Port Power enable signal for USB port 2.
MISO1 — Master In Slave Out for SSP1.
AD0[6] — A/D converter 0, input 6.
P0[13] — General purpose digital input/output pin.
USB_UP_LED2 — USB port 2 GoodLink LED indicator. It is LOW when device is
configured (non-control endpoints enabled), or when host is enabled and has
detected a device on the bus. It is HIGH when the device is not configured, or
when host is enabled and has not detected a device on the bus, or during global
suspend. It transitions between LOW and HIGH (flashes) when host is enabled
and detects activity on the bus.
MOSI1 — Master Out Slave In for SSP1.
AD0[7] — A/D converter 0, input 7.
P0[14] — General purpose digital input/output pin.
USB_HSTEN2 — Host Enabled status for USB port 2.
USB_CONNECT2 — SoftConnect control for USB port 2. Signal used to switch
an external 1.5 k resistor under software control. Used with the SoftConnect
USB feature.
SSEL1 — Slave Select for SSP1.
P0[15] — General purpose digital input/output pin.
TXD1 — Transmitter output for UART1.
SCK0 — Serial clock for SSP0.
SCK — Serial clock for SPI.
P0[16] — General purpose digital input/output pin.
RXD1 — Receiver input for UART1.
SSEL0 — Slave Select for SSP0.
SSEL — Slave Select for SPI.
