Microprocessor Interface

The microprocessor interface comprises 13-lines. Two

address bits provide four addresses for device programming

and CLUT/register management. Address bit 0 selects

between control registers and CLUT memory. Address bit 1

selects between reading/writing the register addresses and

reading/writing register or CLUT data.

When writing, the address is presented along with a LOW on

the R/W pin during the falling edge of CS. Eight bits of data

are presented on D7-0 during the subsequent rising edge of

CS.

One additional falling edge of CS is needed to move input

data to the assigned working registers.
