Bit 0 ~ Bit 1 :
(undefined) not allowed to use
Bit 2(P5SH) : Switch I/O PORT5 high nibble(5~7) or LCD segment signal
0
(P55 ~ P57 pins are selected) : normal PORT5 high nibble(5~7)
1
(SEG10 ~ SEG12 pins are selected) : SEGMENT output

Bit 0 ~ Bit 7 (T10 ~ T17) : Tone generator 1‘s frequency divider and power control
Please Run in Normal mode.
Clock source = 111957Hz and Freq. = 111957Hz / N, where N is divider value for T1A ~ T10 (T1A ~ T18
are in the IOCE PAGE0 Bit 2 ~ Bit 0.
If T20 ~ T18 are all “0”, then
T17 ~ T10 = ‘11111111’ => Tone generator1 will has 439Hz SIN wave output.
:
T17~T10 = ‘00000010’ => Tone generator1 will has 55978Hz SIN wave output.
T17~T10 = ‘00000001’ => DC bias voltage output
T17~T10 = ‘00000000’ => Power off
