Description
Reference_Lock - this bit will be HIGH when the output
is successfully genlocked to the input (i.e. when bits 4-1
of this register are HIGH and are not masked by bits 4-2
of register 16h).
The LOCK_LOST output pin is an inverted copy of this
bit.
Reference:
F_Lock - this bit will be HIGH when the output F is
successfully genlocked to the FSYNC input.
NOTE: If the input reference does not include an
FSYNC input, this bit will have the same setting as
V_Lock (bit 3).
Reference:
V_Lock - this bit will be HIGH when the output V is
successfully genlocked to the VSYNC input.
Reference:
H_Lock - this bit will be HIGH when the output H is
successfully genlocked to the HSYNC input.
Reference:
Clock_Lock - this bit will be HIGH when the video clock
is locked to the internal V_pll AND the audio clock is
locked to the internal A_pll (i.e. bits 0 and 1 of register
1Fh are HIGH).
Reference:
Reference_Present - this bit will be HIGH when a valid
input reference signal has been applied to the device.
The REF_LOST output pin is an inverted copy of this
bit.
