Description
Set the lower nibble of the column
address pointer for RAM access. The
pointer is reset to 0 after rest.
Set the upper nibble of the column
address pointer for RAM access. The
pointer is reset to 0 after rest.
The internal regulator gain
(1+R2/R1)Vout increases as R2R1R0 is
increased from 000b to 111b. The
factor,
1+R2/R1, is given by:
R2R1R0 = 000: 2.84 (POR)
R2R1R0 = 001: 3.71
R2R1R0 = 010: 4.57
R2R1R0 = 011: 5.44
R2R1R0 = 100: 6.30
R2R1R0 = 101: 7.16
R2R1R0 = 110: 8.03
R2R1R0 = 111: 8.89
VC=0: turns OFF the internal voltage
booster (POR)
VC=1: turns ON the internal voltage
booster
VR=0: turns OFF the internal regulator
(POR)
VR=1: turns ON the internal regulator
VF=0: turns OFF the output op-amp
buffer (POR)
VF=1: turns ON the output op-amp
buffer
The second command specifies the row
address pointer (0-79) of the RAM data
to be displayed in COM0. This
command has no effect on ICONS. The
pointer is set to 0 after reset.
The second command specifies the
mapping of first display line (COM0) to
one of ROW0~79. This command has
no effect on ICONS. COM0 is mapped
to ROW0 after reset.
The second command specifies the
number of lines, excluding ICONS, to
be displayed. With Icon is disabled
(POR), duties 1/16~1/80 could be
selected. With Icon enabled, the
available duty ratios are 1/17~ 1/81.
