Sub-carrier Value Register
Registers FSCI contain a 32-bit value which is used as an increment value for the ROM address generation circuitry when
CIVEN=0. The bit locations are specified as follows:
Register
0Ch
0Dh
0Eh
0Fh
When the CH7009 is used in the master clock mode, the tables below should be used to set the FSCI registers. When
using these values, the CIVEN bit in register 10h should be set to ‘0’, and the CFRB bit in register 02h should be set to
‘1’.
