[5:0] SYSCLKDIV System Clock Divider Configuration. The system clock divider is used to provide a divided
clock from the root clock, which drives the peripheral bus, die to die interface, and most digital
peripherals. System clock frequency (f
SYS
) = root clock/SYSCLKDIV. Value range is from 1 to
32. Values larger than 32 are saturated to 32. Value 0 and Value 1 have the same results as
divide by 1. f
SYS
must be ≤16 MHz. Characterization is completed only with analog die system
clock of 4 MHz, 8 MHz, and 16 MHz.
