III.4 - Microprocessor Interface
III.4.1 - Description
The Multi-HDLC circuit canbe controlledby several
types of microprocessors (ST9, Intel/Motorola 8 or
16 data bits interfaces) such as :
- ST9 family
- INTEL 80C188 8 bits
- INTEL 80C186 16 bits
- MOTOROLA 68000 16 bits
- MOTOROLA 68020 16/32 bits
- ST10 family
During the initialization of the Multi-HDLC circuit,
the microprocessor interface is informedof the type
of microprocessor that is connectedby polarisation
of three external pins MOD 0/2).
Two chip Select (CS0/1)pins are provided.CS0 will
