5.2
In addition to the input bit delay feature, the ZL50017 allows users to change the sampling point of the input bit by
programming STIN[n]SMP 1-0 (bits 5 - 4) in the Stream Input Control Register 0 - 15 (SICR0 - 15). For input
streams the default sampling point is at 3/4 bit and users can change the sampling point to 1/4, 1/2, 3/4 or 4/4 bit
position.
