10.3.13 NICAM LOWER ERROR LIMIT REGISTER
When the auto-mute function is enabled (bit AMUTE in the
NICAM configuration register) and the NICAM bit error
count is lower than the value contained in this register, the
NICAM signal is selected (again) for reproduction
(see Section 10.3.14).
Table 34 Subaddress 16 (notes 1 and 2)
Notes
1. The default setting at power-up is 0001 0100.
2. The lower bit error rate
limit
subaddress 16 × 1.74 × 105.
10.3.14 NICAM UPPER ERROR LIMIT REGISTER
When the auto-mute function is enabled (bit AMUTE in the
NICAM configuration register) and the NICAM bit error
count is higher than the value contained in this register, the
signal of the first sound carrier (i.e. FM mono or AM sound)
or the external mono input (depending on bit AMSEL and
ADC output selection) is selected for reproduction.
The difference between upper and lower error limit
constitutes a hysteresis to avoid frequent switching
between NICAM and the program on the first sound
carrier.
Table 35 Subaddress 17 (notes 1 and 2)
Notes
1. The default setting at power-up is 0101 0000.
2. The upper bit error rate
limit
subaddress 17 × 1.74 × 105.
