IDT82V2608
Inverse Multiplexing for ATM
3.3
EXTERNAL MICROPROCESSOR INTERFACE
The IDT82V2608 uses an embedded controller and a downloaded
software (IMAOS08 or IMAOS08_Slave
1
) to communicate with the
external mcroprocessor. The external mcroprocessor sends commands
to configure the device and read feedbacks. The downloaded software
interprets these commands and the embedded controller executes
these commands. This relieves programmers fromaccessing vast regis-
ters. Just by accessing a few registers, programmers can use a set of
well-defined commands to communicate with IDT82V2608.
3.3.1
EXTERNAL MICROPROCESSOR INTERFACE SELECTION
The IDT82V2608 supports both non-multiplexed Intel and non-multi-
plexed Motorola mcroprocessor interfaces. For Intel mcroprocessor
interface, the MPMpin should be connected to VDD; for Motorola mcro-
processor interface, the MPMpin should be connected to ground.
3.3.2
COMMAND FIFOS
The embedded controller uses two FIFOs to communicate with the
external mcroprocessor. One is Input FIFO, which is used to receive
commands and data fromthe external mcroprocessor; the other is
Output FIFO, which is used to send data to the external mcroprocessor.
The lengths of these two FIFOs are both 16 bytes. These two FIFOs can
only be accessed through registers.
3.3.3
REGISTERS
The IDT82V2608 provides 9 registers for the external mcropro-
cessor to load software to the device, send commands and read feed-
backs.
3.3.4
REGISTER MAP
1. IMAOS08 is used when the device is in normal communication while
IMAOS08_Slave is used when the device operates in Slave Mode. Refer to
