MB90660A Series
I
MASK OPTION LIST
Notes: A specification of “yes” for accept asynchronous reset input refers to a function whereby reset input is
accepted when oscillation for output ports (including peripheral resource output) is stopped and port output
(including peripheral resource output) is forced Hi-z. Note, however, that since internal reset (reset of the
CPU and peripheral resources) is synchronized with the clock, the CPU and peripheral resources are not
initialized when the clock is stopped.
For details on writing to the MB90P663A, see Chapter 6, “
I
PROGRAMMING THE MB90P663A EPROM”.
Use of a pull-up/pull-down resistors for the mode pins (MD2 to MD0) can be selected separately for each
pin. If “yes” is selected, a pull-up is attached to MD0 and MD1 and a pull-down to MD2 for mask ROM
versions. A pull-up is attached to MD0 and MD1, but a pull-down is not attached to MD2 for OTP versions.
Since it takes eight machine cycles to make option settings for the MB90P663A, options cannot be set
between when power is first turned on and the clock is supplied. (This results in a setting of no pull-up for
all pins and accept asynchronous reset input.)
No.
