Targ et Preferences

Clock phase

Select

No_delay or Delay_half_cycle.

Clock polarity

Select

Rising_edge or Falling_edge.

Data bits

Length in bits from

1 to 16 of each transmitted or received

character. For example, if you select

8, the maximum data

that can be transmitted using SPI is

8-1

.Ifyousenddata

greater than this value, the buffer overﬂows.

Enable Loopback

Select this option to enable the loopback function for

self-test and diagnostic purposes only. When this function is

enable d, the Tx pin on a C28x DSP is internally conn ected

to its Rx pin and can transmit data from its o utput port to

its input port to check the integrity of the transmission.

Enable FIFO

Set true or false.

FIFO interrupt level (Rx)

Set level for receive FIFO interrupt. Select

0 through 16.

FIFO interrupt level (Tx)

Set level for transmit FIFO interrupt. Select

0 through 16.

FIFO transmit delay

Enter FIFO transmit delay (in processor clock cycles) to

pause betwe en data transmissions. Enter an integer.

Mode

Set to

Master or Slave.

CLK pin assignment

Assigns the SPI something (CLK) to a GPIO pin. Choices

are

None (default), GPI014,orGPI026.

SIMO pin assignment

Assigns the SPI something (SIMO) to a GPIO pin. Choices

are

None (default), GPI012,orGPI024.
