7.3.14
NICAM LOWER ERROR LIMIT REGISTER (NLELR)
When the auto-mute function is enabled
(see Section 7.3.12) and the NICAM bit error count is
lower than the value contained in this register, the NICAM
signal is selected (again) for reproduction; see also
Section 7.3.15.
The default setting after Power-on reset is 0001 0100.
Table 41 NICAM lower error limit register
(subaddress 16)
7.3.15
NICAM UPPER ERROR LIMIT REGISTER (NUELR)
When the auto-mute function is enabled 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 analog mono input is selected for
reproduction.
The difference between the upper and lower error limit
constitutes a hysteresis to avoid frequent switching
between NICAM and the program on the 1st sound carrier.
The default setting after Power-on reset is 0101 0000.
Table 42 NICAM upper error limit register
(subaddress 17)
7.3.16
AUDIO MUTE CONTROL REGISTER (AMCONR)
Only bits 6, 2 and 1 are used. When any of these bits is set
to logic 1, the corresponding pair of output channels will be
muted. A bit set to logic 0 allows normal signal output.
The unused bits should be set to logic 1
The default setting after Power-on reset is 1111 1111.
