MODE
B
Input pins for setting the memory access mode.
Connect directly to VSS.

RST
C
Reset I/O pin. The pin is a N-ch open-drain type with pull-
up resistor and a hysteresis input. The pin outputs a “L”
level when an internal reset request is present. Inputting
an “L” level initializes internal circuits.
