Logic

 

Notes: The Chip Select Logic shown above is necessary to guarantee timing parameter t1 of the Generic MPU Interface Asynchronous Timing (for details refer to the S1D13504 Hardware Functional Specification, document number X19A-A-002-xx).

When connecting the S1D13504 RESET# pin, the system designer should be aware of all conditions that may reset the S1D13504 (e.g. CPU reset can be asserted during wake-up from power-down modes, or during debug states).
