DCLK counter error. Make sure to enable the corresponding error in the diagnostic control

0 Disables pin toggle for internal errors.

1 Enables pin toggle for internal errors.

ERR_PIN_EN_SPI

Enables error reporting on GPIO7 if there are any SPI errors such as read, write, CRC

check, and clock counter errors. Make sure to enable SPI CRC error for reporting those

errors on the pin.

ERR_PIN_IN_STATUS

This bit is the readback of the latched status of the error input, GPIO6, when it is enabled

using the ERR_PIN_IN_EN bit.

0x0

ERR_PIN_IN_EN

Enables GPIO6 as an error input. This bit allows error to be daisy-chained from a digital host

and is OR’ed with internal errors.

0x0

R/W

ERR_PIN_OUT_EN

Enables GPIO7 as an error output pin. The source of this error is defined by the

ERROR_PIN_SRC_CONTROL register.
