When REG[F0h] Bit-3 is ‘1’, the data in the REG[E0h] will be filled to
the whole active window.

When this bit is set to “1”, RA8806 will automatically read PNTR data,
and fill it to Active window (Range: [AWLR, AWTR] ~ [AWRR,
AWBR]), after clear completed, this bit will be cleaned to “0”.
ASCII Mode Enable
1 : All input data will be decoded as ASCII (00h ~ FFh)
0 : In text mode (REG[00h] Bit-3), the RA8806 will check the first
