EPSON
SED1225 Series
Reset Circuit
When the RES input is made active, this LSI is initialized.
Initialization status
(1) Display ON/OFF control
C=0:
Cursor off
B=0:
Blink off
DC=0:
Normal display
D=0:
Display off
(2) Power save
O=0:
Oscillating circuit off
PS=0:
Power save off
(3) Power control
P=0:
Power circuit off
(4) System set
N=0:
3 lines
S2, S1=0:
Direction of normal display
CG=0:
CGRAM unused
(5) Electronic control
Address:
28H
Data:
(0,0,0,0,0)
(6) Static icon
Address:
20H to 23H
Data:
(0,0,0,0,0)
(7) LED register
Address:
2AH
Data:
(0,0,0,0,0)
(8) CG RAM, DD RAM and symbol register
Address:
00H to 1FH, 30H to 7CH
Data:
Must be initialized by MPU after
reset input because of being
indefinite.
Connect the RES terminal to the MPU reset terminal as
described in “6-1 MPU Interface”, and execute
initialization simultaneously with the MPU. However, if
the MPU bus and port are put into high impedance for a
certain time period by resetting, perform reset input to the
SED1225 after the input to the SED1225 has been
determined. When the RES terminal becomes “L”, each
register is cleared and the above setup is established. If
initialization by the RES terminal is not performed when
power voltage is applied, resetting may be disabled.
