Bit [7:4] : 24V1 [3:0] 4-bit data value determines the divider value for the 24V1 system-clocking signal. Note that the
4-bit data value equals n-1, where n is the desired divider value, as illustrated in
See
Bit [3:0] : 24V2 [3:0] 4-bit data value determines the divider value for the 24V2 system-clocking signal. Note that the
4-bit data value equals n-1, where n is the desired divider value, as illustrated in the
nals. See
