M48T86
Operation
2.1.11
R/W (read/write input)
The R/W pin is used to latch data into the M48T86 and provides functionality similar to W in
other memory systems.
2.1.12
Non-volatile RAM
The 114 general-purpose non-volatile RAM bytes are not dedicated to any special function
within the M48T86. They can be used by the processor program as non-volatile memory
and are fully accessible during the update cycle.
