MB90660A Series
4. PROM Option Bitmap
The programming method is the same as a PROM, and can be set by programming values to addresses indicated
in the memory map.
The following bit map shows the relation between bits and options.

Initially (value when blank), all bits are “1”.
*1: Under this release, the pull-up resistor is cut-off during stop mode for pins for which the pull-up option was
selected. (Pins for which the circuit type shown in the “s Pin Description” is B or E.)
However, the pull-up resistor is not cut-off even in stop mode for P44 to 47, RST, DTTI (pins for which the circuit
type shown in the “s Pin Description” is D or G), and MD1 and MD0.
*2: Whether or not a pull-up/pull-down resistor is present for MD2, MD1 and MD0 is determined as follows. If pull-
up/pull-down resistor is selected, it is included with all 2 (or 3) pins. Presence or absence of the pull-up or pull-
down resistors for the mode terminal cannot be selected for each pin.

Notes: • “FFH” must be set to addresses no defined in the table above.
• Since the option setting for the MB90P663A takes 8 machine cycles, the option setting is not made until
a clock is provided after power-on. (This results in no pull-up for all pins, and asynchronous reset input is
accepted.)
