Interrupt Enable flag Control
The interrupt enable flag corresponding to the data specified by I7-I0 is
controlled:
I0~I7
Operation
I0 = 1
I1 = 1
I2 = 1
I4 = 1
I5 & I6
The IEF0 is set so that interrupt 0 (overflow from the
divider 0) is accepted.
The IEF1 is set so that interrupt 1 (underflow from the
Timer 0) is accepted.
The IEF2 is set so that interrupt 2 (signal change at port
RC) is accepted.
The IEF4 is set so that interrupt 4 (overflow from the
divider 1) is accepted for W741C260 body;
the IEF4 is set so that interrupt 4 (falling edge signal
at the INT pin) is accepted for the W741C250 body.
I7 = 1
Reserved
The IEF7 is set so that interrupt 7 (underflow from the
Timer 1) is accepted.

Select LCD output mode type
When LCD output pins are set to DC output mode, user can select CMOS
or NMOS as output type.
I0~I7 = 0 => CMOS type; I0~I7 = 1 => NMOS type.
