Graphics controller for the Sitronix ST7549

Hi,

Has anyone ever written a display driver for this GLCD controller in parallel or 3-wire SPI mode? (16 wire interface)

pinout includes:
---------------
1 Vout
2 Vss
3 D0
4 D1
5 D2
6 D3
7 D4
8 D5
9 D6
10 D7
11 A0
12 RD
13 WR
14 CSB
15 RESET
16 Vdd


Does anyone know if this is functionally close to the KS0107 or some other controller? I've found code examples in 'c' for KS0107 and a few other but not for the ST7549, not sure why. The datasheet leaves a bit to be desired.

thanks.
