Table 5.6 Example of rewriting procedure of data 384 KBytes (30000h Bytes) of
microcode
Transfer example 1:
1) CMD = 92h SN, SC = 0100h FR = 0lh
2) CMD = 92h SN, SC = 0100h FR = 0lh
3) CMD = 92h SN, SC = 0100h FR = 0lh
4) CMD = 92h SN, SC = 0000h FR = 07h
Transfer example 2:
1) CMD = 92h SN, SC = 0300h FR = 0lh
2) CMD = 92h SN, SC = 0000h FR = 07h
Transfer example 3:
1) CMD = 92h SN, SC = 0300h FR = 07h
Transfer example 4:
1) CMD = 92h SN, SC = 0100h FR = 0lh
2) CMD = 92h SN, SC = 0100h FR = 0lh
3) CMD = 92h SN, SC = 0100h FR = 07h
When the data of the transfer microcode did the rewriting specification with the
