RX_SAMPLE_DLY
RX Sample Delay.
This register is only valid when the DW_apb_ssi is configured with rxd
sample delay logic (SSI_HAS_RX_SAMPLE_DELAY==1). When the DW_apb_ssi is
not configured with rxd sample delay logic, this register will not exist
and writing to its address location will have no effect; reading from
its address will return zero. This register control the number of ssi_clk
cycles that are delayed (from the default sample time) before the actual
sample of the rxd input occurs. It is impossible to write to this
register when the DW_apb_ssi is enabled. The DW_apb_ssi is enabled and
disabled by writing to the SSIENR register.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

Rxd Sample Delay. This register is used to delay the sample of the rxd input port. Each value represents a single ssi_clk delay on the sample of rxd. Note; If this register is programmed with a value that exceeds the depth of the internal shift registers (SSI_RX_DLY_SR_DEPTH) zero delay will be applied to the rxd sample. |
