Seiko Instruments Inc.
Operation
1. Power-on
After power-on, initialization is executed by either the rising or the falling edge of the RESX input. MPU Interface
mode is selected by the level after RESX signal changes.
When initialization by RESX and the selection of an interface are not executed at power-on, a malfunction may
occur. Since chattering in RESX causes poor initializaition and erroneous selection of MPU interface, input the
signal without chattering. For details, refer to Reset and MPU Interface Selection in this section.
2. Reset
The S-4520BA can be initialized through RESX input or Reset command.
The initialization items through RESX input are listed in Table 9. Initialization through RESX input is executed at
the signal change point, either rising or falling. At that time, it is possible to select the MPU Interface. When
executing RESX input during operation at power-on, it is necessary to set the signal polarity to fixed MPU.
Initialization through Reset command executes , , and in Table 9. Be aware of the difference in
initialization items between reset through RESX input and initialization through Reset command.

3. MPU interface selection
The selection of the S-4520B Series interface is determined by RESX signal logic after RESX signal input.
It is possible to connect directly to either the 68 family or the 80 family MPU
