Controller Chip for DP

Compatibility:
Under the condition of 3.3v working voltage, it is fully compatible with the VPC3 operating in DPV0 mode.
It is fully compatible with SPC3 operating in DPV0 mode except for the operating voltage

Processor interface:
Support Intel and Motorola two processor interface mode; The interface MODE can be configured through XINT/MOT and MODE pins.
With a synchronous/asynchronous 8-bit data interface and an 11-bit address bus, users can directly manipulate internal dual-port RAM

The clock:
APC3 needs to provide a 48MHZ external clock;
APC3 can output 24M/12M clocks to external processors

Software interface:
APC3 integrates 1.5k dual-port RAM, which is mainly used for the interface between APC3 and software;
Dual-port RAM is divided into 192 segments, each containing 8 bytes.Software operates on two-port RAM in segments
