CIV Control Register
CIVEN (bit 0) of register CIVC controls whether the FSCI value is used to set the sub-carrier frequency, or the
automatically calculated (CIV) value. When the CIVEN value is ‘1’, the number calculated and present at the CIV
registers will automatically be used as the increment value for sub-carrier generation. Whenever this bit is set to ‘1’, the
CFRB bit should be set to ‘0’.
PALN (bit 1) of register CIVC forces the CIV algorithm to generate the PAL-N (Argentina) sub-carrier frequency when
it is set to ‘1’. When this bit is set to ‘0’, the VOS[1:0] value is used by the CIV algorithm to determine which sub-
carrier frequency to generate.
CIVC[1:0] (bits 3-2) of register CIVC control the hysteresis circuit which is used to calculate the CIV value. The default
value should be used.
