REGISTERS
5.1 Register Mapping
The C332L01 maps the SID13705 block registers to the 32 bytes from 0x039FFE0 through
0x039FFFF.
5.2 Register Descriptions
Unless specified otherwise, all register bits are reset to 0 during power up.
All bits marked n/a should be programmed 0.
bits 7-2
Product Code
This is a read-only register that indicates the product code of the chip. The product code
is 001001.
bits 1-0
Revision Code
This is a read-only register that indicates the revision code of the chip. The revision
code is 01.
bit 7
TFT/STN
When this bit = 0, STN (passive) panel mode is selected. When this bit = 1, TFT/D-
TFD panel mode is selected. If TFT/D-TFD panel mode is selected, Dual/Single
(REG[01h] bit 6) and Color/Mono (REG[01h] bit5) are ignored. See Table 5-1 for a
comprehensive description of panel selection.
bit 6
Dual/Single
When this bit = 0, Single LCD panel drive is selected. When this bit = 1, Dual LCD
panel drive is selected. See Table 5-1 for a comprehensive description of panel selec-
tion.
bit 5
Color/Mono
When this bit = 0, Monochrome LCD panel drive is selected. When this bit = 1, Color
LCD panel drive is selected. See Table 5-1 for a comprehensive description of panel
selection.
bit 4
FPLINE Polarity
This bit controls the polarity of FPLINE in TFT/D-TFD mode (no effect in passive
panel mode). When this bit = 0, FPLINE is active low. When this bit = 1, FPLINE is
active high.
bit 3
FPFRAME Polarity
This bit controls the polarity of FPFRAME in TFT/D-TFD mode (no effect in passive
panel mode). When this bit = 0, FPFRAME is active low. When this bit = 1, FPFRAME
is active high.
