EPSON
SED1240 Series
Power control (1)
Function: Controls the operation of the built-in power
circuit.
Boosting circuit ON/OFF is specified by setting P.
For operating the boosting circuit, the oscillating
circuit must be in operation.
P
= 0
: Boosting circuit OFF
P
= 1
: Boosting circuit ON
Voltage follower ON/OFF is specified by setting VF.
VF
= 0
: Voltage follower OFF
VF
= 1
: Voltage follower ON
Voltage regulating circuit ON/OFF is specified by
setting VC.
VC
= 0
: Voltage regulating circuit OFF
VC
= 1
: Voltage regulating circuit ON.
High power mode ON/OFF is specified by setting
HPM.
HPM
= 0
: High power mode OFF
HPM
= 1
: High power mode ON
Power control (2)
Function: Controls the operation of the built-in power
circuit.
The relation of IR0 and option combinations is shown
in the following table.
Bias selection is performed by setting BAS.
BAS
= 0
: 1/5 bias
BAS
= 1
: 1/4 bias
Either built-in V5 voltage regulating resistor or external
resistor (no use of built-in resistor) is selected by
setting IRS.
IRS
= 0
: No use of built-in resistor
IRS
= 1
: Use of built-in resistor
System set (1)
Function: Selects an option ROM and sets the common
shift direction and the use/no use of CGRAM.
The relation of R1 and R0 combinations is shown in
the following figure.
The COM shift direction is specified by setting CS.
CS
= 0
: COM left shift
(COM1
→ COM32 →
COMS1
→ COMS2)
CS
= 1
: COM right shift
(COM32
→ COM1 →
COMS1
→ COMS2)
The use/no use of CGRAM is specified by setting CG.
CG
= 0
: No use of CGRAM
CG
= 1
: Use of CGRAM
System set (1)
Function: sets the normal/reverse display of SEG
characters.
This function operates for each character.
The normal/reverse display of SEG is specified by
setting SS.
SS
= 0
: Normal display of SEG
SS
= 1
: Reverse display of SEG
For the symbol register RAM output, only the normal
display is available.
