1: SECTION control
0: STPC control
1: Off
0: On
1: IR output carrier with duty cycle 75%
0: IR output without carrier
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.

Bits 5-7 of PAGE register are reserved; bits 0-4 are used for page selection. The user must setup the
page mode configuration described in the Option Control Function section. Once the page mode is
decided, the working page is selected by the bits 0-4 of PAGE register. Hence, the user can execute
"LD PAGE, value" instruction to change the working page of the voice entry group. Not all of the bits
0-4 of PAGE register are used in different page mode; they are listed below.
