6.2.1.69. RX_CLK_POST

Offset: 0x55
Default: IP Param
Description: RX_CLK_POST
Bit Name Access Description
7:0 RX_CLK_POST Read Write *

RX_CLK_POST

This is only used for continuous clock mode.

Protocol specifies the minimum number of clock cycles required after end of data transmission before it is safe to gate the Rx Clock for periodic Rcomp.

Delay computation (approx):

TRX-CLK_POST_= (RX_CLK_POST + 3) * RX_CLK_period + 5 * Core_CLK_period.
Note: * Can be configured as Read Only during IP generation to save resources.
