Table 1. Control Registers
IDENTIFICATION AND MEMORY ADDRESS BYTES
The first byte sent to the X79000, following a falling edge
at the CS pin, is called the “Identification Byte”. The most
significant bit (ID7) is the function selector bit. The next
six bits (ID6-ID1) are the Device Address bits (AS5-AS0).
To communicate to the X79000, the value of bits AS[5:0]
must correspond to the logic levels at pins A5, A4, A3,
A2, A1, and A0 respectively. If one or more of the
address pins doesn’t exist in a particular device, then the
corresponding device address bits must be set to “0”.
The LSB (ID0) is the R/W bit. This bit defines the
operation to be performed on the device being
addressed. When the R/W bit is “1”, then a Read
operation is selected. A “0” selects a write operation.
If the value of the Device Address bits doesn’t match the
logic levels at the Address pins, then the Read or Write
operation is aborted.
The byte sent to the X79000, immediately following the
Identification byte, is called the Memory Address Byte.
The value of this byte is the location of the first byte to
be written to, or read from the X79000. Valid values for
this byte are from 00h to 3Fh. If the value of the
“Memory Address byte” is invalid, the Read or Write
operation is aborted.
