The following programming ranges and restrictions are valid:
- The programmed values of [7-0] INFIFO_THRESHOLD and [23-16] OUTFIFO_THRESHOLD register bitfields should be within 1-32 range. This applies to ASRC_SRCFFCTRL_0 and ASRC_GFFCTRL_0 registers.
- Only the following settings for [16-9] LOOP_SETUP bit-field are allowed: 8’h00, 8’h40, 8’h80, 8’hC0. This applies to SRC_ICKZCTRL_0 and ASRC_OCKZCTRL_0 registers.
- ASRC_IGRPSEL_0 to ASRC_IGRPSEL_3 and ASRC_OGRPSEL_0 to ASRC_OGRPSEL_3 registers should have same channels enabled for group number 0 to 3.
