FUNCTIONAL MODES
There are two primary functional modes for operation: external processor only or simultaneous internal and external
processor operation.
External Processor Control
In this mode of operation the external processor can access all internal registers via the IC interface and receive
interrupts via an interrupt pin, and the internal Microcontroller can be powered down or clock gated off.
Combined Internal and External Processor Operation
In this mode of operation the Microcontroller in the P95020 will function autonomously or semi-autonomously based on
the content of the on-board or external ROM. The external Application Processor may or may not perform additional
control functions through the IC bus interface. Individual time-based or event-based interrupts generated inside the
P95020 device may be routed internally or externally to be handled separately. All IC registers can be simultaneously
accessed by either the external Application Processor or the internal Microcontroller. Access to the I
2C registers is
arbitrated via on-chip hardware arbitration.
