Revision Description
1. Added Bit 1(CDAR) for the Code Option Register for
current D/A.
2. Modified the current D/A reference current value from
“0” to “0 or 0.3125mA” option while setting VOL3 ~
VOL0 =0. This option is controlled by Code Option
Register Bit 1(CDAR)
3. Revised the spec description:
(1) Revised "PS9" to "PSW9" in Item 4 of User
Application Note
(2) Revised "Fig.4" to "Fig.3"
(3) Revised "Bit 0 I :" to "Bit 0 (C)"
(4) Removed the note in R4 register
(5) Removed "Bit 4: unused" and revised "Bits 5~7" to
"Bits 4~7"
(6) Revised “Fig.16" to "Fig.4" in CONT Bit 5
(7) Revised "Bit 0 ~ Bit 3" to "Bit 4~Bit 6" in IOC5
Page 1
(8) Revised “IOC6 Page 1,"Page 1 (Voice ROM
ddress (16~18))" to "Page 1 (VRAH: Voice ROM
address(16~18))"
(9) Revised "VRAH" to "VRAM" in IOC7
(10) Revised the no. of keyscan steps
(11) Modified "1.5826MHz" to "3.5826MHz" in EGCLK
register
(12) Revised the description "has 60 segments and 16
commons that can drive 60*16 dots totally" to "has
40 segments and 8 commons that can drive 40*8
dots totally"
(13) Removed “For VDD = 3.3V, the /POVD reset
voltage” in section 7.9 Code Option Register
Modified the spec description:
1. Modified the voice ROM size from 300K×4 to 304K×4
2. Modified (IOC6~IOC8) Page 1 description about voice
ROM
Updated the pin configuration
1. Deleted the descriptions for ICE807C
2. Modified the note on the I/O port description
