Function Documentation

sense_link_status_count()

unsigned sense_link_status_count

(

const sense_link_t *

s

)

The registers a SENSE status read takes.

Parameters

s	The link state.

Returns

SENSE_LINK_STATUS_COUNT when the AS5600 part is enabled or the INA3221 windows come from SERVO_WIN, else SENSE_LINK_STATUS_COUNT_V48.

sense_link_write_owed()

sense_link_op_kind_t sense_link_write_owed	(	const sense_link_t *	s,
		uint16_t *	regs )

The write owed now, or NONE, with its registers in regs.

Parameters

s	The link state.
regs	Receives the registers of the write.

Returns

The write owed, or NONE, as sense_link_op_kind_t.
