RESET CIRCUIT
The M37220M3-XXXSP is reset according to the sequence shown
in Figure 41. It starts the program from the address formed by using
the content of address FFFF
16
as the high-order address and the
content of the address FFFE
16
as the low-order address, when the
RESET pin is held at “L” level for 2
μ
s or more while the power source
voltage is 5 V ± 10 % and the oscillation of a quartz-crystal oscillator
or a ceramic resonator is stable and then returned to “H” level. The
internal state of microcomputer at reset are shown in Figure 43.
An example of the reset circuit is shown in Figure 42.
The reset input voltage must be kept 0.6 V or less until the power
source voltage surpasses 4.5 V.

Notes 1
:
f(X

) and f(

) are in the relation : f(X

) = 2·f (

).
2:
A question mark () indicates an undefined state that
depends on the previous state.
Immediately after a reset, timer 3 and timer 4 are
connected in hardware. At this time, “FF
16
” is set
in timer 3 and “07
16
” is set to timer 4. Timer 3 counts down
with f(X
IN
)/16, and reset state is released by the timer 4
overflow signal.
