Example of Programming the FSK-RAM via GCI
FSK-RAM write command (The address is '00001', means that data will be written to word 2 and word 1.)
FSK-RAM read command (The address is '00001', means that word 2 and word 1 will be read.)
Program Start byte
data read out from low byte of word 8 in block 1
data read out from high byte of word 7 in block 1 (the highest two bits (b7b6) are meaningless)
data read out from low byte of word 7 in block 1
data read out from high byte of word 6 in block 1 (the highest two bits (b7b6) are meaningless)
data read out from low byte of word 6 in block 1
data read out from high byte of word 5 in block 1 (the highest two bits (b7b6) are meaningless)
