TDM Timing
Values are based on a a maximum frequency of 62.5 MHz. The TDM interface supports any frequency below 62.5 MHz.
Values are based on 20 pF capacitive load.
When configured as an output, TDMxRCLK acts as a second data link. See the MSC8126 Reference Manual for details.
CLKOUT synchronization is not supported for cores operating at above 400 MHz.
Values are based on 10 pF capacitive load.
