ROM

The ROM consists of 8 banks. Each bank provides 2 x 64 bytes. Please refer to the diagram below.

A bank is selected by using flip flops BS0 to BS2 which are the 3 highest address bits. In a single

system, these bits are loaded from the 3 MSBs of the Scan Control when KI0 = ”0”. During Power-On,

the bank select flip-flops will be in an arbitrary state.

When a key is activated, the key number if stored in the 6-bit key register. This register forms the lower

bits of the ROM Address. For each command, the ROM will be accessed twice giving a total of 16 bits

(M0L to M7L and M0H to M7H). The table below describes these bits.
