PTP_IO2

Ethernet Precision Time Protocol I/O 2

Note: Used for PTP input control and output events. Programmable as either a push-pull

output, an open-drain output, or a Schmitt-triggered input.

PTP_IO3

Ethernet Precision Time Protocol I/O 3

Note: Used for PTP input control and output events. Programmable as either a push-pull

output, an open-drain output, or a Schmitt-triggered input.

PTP_IO4

Ethernet Precision Time Protocol I/O 4

Note: Used for PTP input control and output events. Programmable as either a push-pull

output, an open-drain output, or a Schmitt-triggered input.

PTP_IO5

Ethernet Precision Time Protocol I/O 5

Note: Used for PTP input control and output events. Programmable as either a push-pull

output, an open-drain output, or a Schmitt-triggered input.

PTP_IO6

Ethernet Precision Time Protocol I/O 6

Note: Used for PTP input control and output events. Programmable as either a push-pull

output, an open-drain output, or a Schmitt-triggered input.

PTP_IO7

Ethernet Precision Time Protocol I/O 7

Note: Used for PTP input control and output events. Programmable as either a push-pull

output, an open-drain output, or a Schmitt-triggered input.

SPI Peripheral Interface Functions

SPI_PERI_CLK

SPI Peripheral Clock

This is the SPI clock input from the SPI controller. If the SPI interface is enabled, this pin

must be driven low during reset.

SPI_PERI_DO

SPI Peripheral Data Out

This is the data out for the SPI port when configured for SPI operation (MISO).

SPI_PERI_DI

SPI Peripheral Data In

This is the SPI data in to the controller from the SPI controller (MOSI). This pin must

have a weak pull-down applied at all times to prevent floating if configured for SPI opera-

tion.

SPI_PERI_CE_N

SPI Peripheral Chip Enable

This is an active low SPI chip enable input. If the SPI interface is enabled, this pin must

be pulled high in power-down states.

SPI_PERI_ALERT_N

SPI Peripheral Alert

SPI Controller Interface 0 Functions

SPI_CTRL0_CLK

SPI Controller 0 Clock

This is the SPI clock output from the SPI controller. If the SPI interface is enabled, this

pin must be driven low during reset.
