Doc ID 16755 Rev 5

Printer mode

The “printer” operating mode mainly provides:

●

NAND Flash interface (8 bits, 4 chip selects)

●

Up to 4 PWM outputs

●

2 SMII interfaces

●

3 UARTs

–

1 with hardware flow control (up to 3 Mbps)

–

1 with hardware flow control (baud rate up to 7 Mbps)

–

1 with software flow control (baud rate up to 7 Mbps)

●

SDIO interface supporting SPI, SD1, SD4 and SD8 mode

●

Standard Parallel Port (SPP device implementation)

●

2 independent SSP Synchronous Serial Ports (SPI, Microwire or TI protocol)

●

GPIOs with interrupt capabilities

●

4.3.3

Alternate functions

Other peripheral functions are listed in the Alternate Functions column of Table 11:

PL_GPIO multiplexing scheme and can be individually enabled/disabled configuring the bits

of a dedicated control register.

4.3.4

Boot pins

The status of the boot pins is read at startup by the BootROM.

4.3.5

GPIOs

The PL_GPIO pins can be used as software controlled general purpose I/Os (GPIOs) if they

are not used by the I/O functions of the SPEAr320 IPs.

To configure any PL_GPIO pin as GPIO, set the corresponding bit in the GPIO_Select(0 ..3)

registers that are 102 bits write registers that select GPIO versus some IPs.
