MODE0.7 controls the output type of LED1 (and LED2) pin. MODE0.6 controls the configuration of
LED2/STPC pin. MODE0.5 controls the output source of IR. If hardware control IR output is selected,
IR output can have signal with carrier or without carrier which is selected by MODE1.0. MODE0.4
controls the trigger pin debounce time. MODE0.2 controls the behavior of the STPA/BUSY pin which
is usually used as Busy signal in CPU mode.

MODE1.5 is for LED flash type control. MODE1.4 is for LED1 section control ON/OFF. MODE1.3 is
for LED2 Section/STPC control. MODE1.2 is for LED1 volume control. MODE1.0 is for IR output with
or without carrier and this bit is useful only MODE0.5 is "1". For STPC control IR output (MODE0.5 is
0), the IR output always has 38 KHz carrier signal no matter what the setting of MODE1.0 is.
