Flash Memory Mode of MB91F367GA/F368GA
To enter the flash memory mode set mode pins MD0 to MD2 to “111”. Assert INITX for at least
500 ns to enter this mode.
The following tables show the pins which are required for the programming procedure and also
describe the states for the pins not used in flash memory mode. Most of the not used pins are
in their reset state (high-Z outputs, enabled inputs). To prevent misbehavior or damage these
pins must be tied to VDD or VSS through resistors - see following tables for details.
Aside from the functional pins described below all power pins should be connected to a power
supply in the specified range, capacitances should be connected to the VCC3C pin as recom-
mended.
