SPI Output Interface Configuration Parameters
TMC4361A provides an SPI output interface. In the next section, the configuration of the
interface parameters is explained in detail.
In order to enable SPI output communication, do as follows:
Action:
 Set serial_enc_out_enable = 0 (bit24 of GENERAL_CONF register 0x00).
Result:
SPI output is enabled.
i SPI out is the default preconfigured setting.
The table below lists the pins that are dedicated to SPI output communication:
SPI Output Communication Pins
Pin
Description
NSCSDRV_SDO

SCKDRV_NSDO
SPI output clock.
SDODRV_SCLK
MOSI – Output pin to transfer the datagram to the
motor driver.
SDIDRV_NSCLK
