All register access can though the I

(1) Mode A Register (Address 00h, RO)

This register consist of a model name and revision number. The upper 4 bits is model_name [3:0] and

the lower 4 bits is rev_num[3:0]. For example it’ s value 12h, this mean 400*300 resolution and

revision2.0 chip.

< model_name >

< rev_num >

400*300 : 0001b

Rev. 2.0 : 0010b

(2) Mode B Register (Address 01h, default : 04h, R/W)

This register defines major operation mode of the chip.
