EXT
: Output voltage of LOT or ROT pin when the
input select 1 is set to the external input 1 or 2
(the data of bits D6 and D5 of subaddress 06H are
“01” or “10”).
V
TV
: Output voltage ROT or LOT pin when the
input select 1 is set to the TV signal (the data of
bits D6 and D5 of subaddress 06H are “00”).
COM pin: Monaural, stereo or SAP signal
(1 kHz, 100 % modulation) input
External input 1 (EL1, ER1 pins), external input 2
(EL2, ER2 pins): No input
Measure the values of the external inputs 1 and 2
