For bare die and wafer products, specified up to 85qC.
The following three circuits are I pin, I/O pin, O pin configurations.
The TEST pin must be grounded and the IM2/1 and IM0/ID pins must be grounded or connected to
Vcc.
This applies to the resistor value (RSEG) between VSH, GND pins and segment signal pins.
Pins: RESET*, CS*, E/WR, RW/RD, RS,
Pins: DB15 -DB2,
OSC1, OPOFF, IM2-1, IM0/ID,TEST
DB1/SD0, DB0/SD1
