Normal operation, VCO in range
VCO out of range
VCO out of range, frequency too low. Only valid if OOR=1
VCO out of range, frequency too high. Only valid if OOR=1
High VCO is active.
Low VCO is active.
DC drive applied to modulators—Non-inverted video at TVOUT
DC drive applied to modulators—Inverted video at TVOUT
Transient output inhibit disabled (that is, speed-up mode)
During this speed-up test mode, ATT = 0 forces sound current source to 1 µA,
while ATT = 1 forces it to 10 µA.
Normal operation
Test pattern generator DC verification (test pattern DC test mode available)
Program divider test (UHF program divider on PLLFILT pin and sound program
divider on SPLLFIL pin)
Reference divider test (UHF reference divider on PLLFILT pin)
UHF phase comparison, upper source on PLLFILT pin
Sound phase comparison 10-µA upper source on SPLLFIL
(only valid during transient output inhibit)
UHF phase comparison, lower source on PLLFILT pin
Sound phase comparison 10-µA lower source on SPLLFIL
(only valid during transient output inhibit)
Sound phase comparison 1-µA upper source on SPLLFIL
(not valid during transient output inhibit)
Sound phase comparison 1-µA lower source on SPLLFIL
(not valid during transient output inhibit)
