LEVEL READ-OUT REGISTERS
These two bytes constitute a word that provides data from
a location that has been specified with the monitor select
register. The most significant byte of the data is stored at
subaddress 5.
If peak-level monitoring has been selected, the peak-level
monitoring register is cleared and monitoring resumes
after its contents has been transferred to these two bytes.
Table 95 Subaddresses 5 and 6
10.4.6
SIF LEVEL REGISTER
When the SIF AGC is on, bits B4 to B0 of this register
contain a number that gives an indication of the SIF input
level. That number corresponds to the AGC gain register
setting (see Section 10.3.1).
When the SIF AGC is off, this register returns the contents
of the AGC gain register.
Table 96 Subaddress 7
10.4.7
TEST REGISTER 3
This register contains, as a binary number, the highest
memory address used for the Coefficient RAM (CRAM,
expert mode).
Table 97 Subaddress 251
10.4.8
TEST REGISTER 2
This register contains, as a binary number, the highest
subaddress used for slave receiver registers.
