This register is used to simplify the setting of different TV
sound standards via the I
will overwrite the contents of registers 3 to 10 with the
settings needed to demodulate one of the standards
shown in Table 70. After power-up, the default setting has
no effect on the settings of registers 3 to 10. Old values of
registers 3 to 10 are not stored. Demodulators filter the
bandwidth and identification time constants are also set
independently from the chosen standard selected in this
register.
This means for I
registers 3 to 10 should not be overwritten during a
refresh.

If ESP is not used, the ESP register should not be
accessed in the refresh routine.
Demodulators filter bandwidth and identification time
constants are also set independently in this register.
The default setting after power-on reset is ‘0000 0000’.
For a description of bits IDMOD0 and IDMOD1 (FM
identification mode), FILTBW0 and FILTBW1
(demodulator filter bandwidth) refer to Section 10.3.7. Bits
IDMOD0 and IDMOD1 (FM identification mode), FILTBW0
and FILTBW1 (demodulator filter bandwidth) are identical
in registers 255 and 9.
