YRAM format
The YRAM block consists of 256 12-bit RAM locations 0 to 255 and is located on the absolute address range of
0800H to 08FFH. The I
2
C-bus transfer consists of 12 useful bits out of 16 bits.

Explanation for the contents of the register bits:
a) D = contents of I
2
C-bus data register bit is don’t care.
b) A = standard I
2
C-bus acknowledge.
c) Number = bit number being useful bit XRAM memory.
d) P = standard I
2
C-bus STOP condition.
Error processing
If a read action is done without first initialising the memory address the acknowledge after the read command will not be
generated by the chip. This should be treated as an error message:
