When this pin is selected to be an output, the buffered clock output register determines which clock is selected to be
output at the DS/BCO clock output pin and what frequency value is output when a VCO derived signal is output.The
tables below show the possible outputs.
Subcarrier Value Registers
Symbol: FSCI
Address: 18H - 1FH
Bits: 4 or 8 each
The lower four bits of registers 18H through 1FH contain a 32-bit value which is used as an increment value for the
ROM address generation circuitry. The bit locations are specified as the following:
