Bit 4
The S1D13704 registers are located in the upper 32 bytes of the 64K byte S1D13704
address range. The registers are accessible when CS# = 0 and AB[15:0] are in the range
FFE0h through FFFFh.
Unless specified otherwise, all register bits are reset to 0 during power up.
Product Code
This is a read-only register that indicates the product code of the chip. The product code is
000110.
Revision Code
This is a read-only register that indicates the revision code of the chip. The revision code is
00.
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 8-1: “Panel Data Format”
below.
Dual/Single
When this bit = 0, Single LCD panel drive is selected. When this bit = 1, Dual LCD panel
drive is selected. See Table 8-1: “Panel Data Format” below.
Color/Mono
When this bit = 0, Monochrome LCD panel drive is selected. When this bit = 1, Color
LCD panel drive is selected. See Table 8-1: “Panel Data Format” below.
