A Comparison between Exar’s XR-88C681 and Motorola’s MC2681 DUART Devices
Figure 1, and allows the CPU to perform Vectored Interrupt Processing and Interrupt
Prioritization for all of the DUART devices.
The MC2681 does not offer the Z-Mode of operation.
2. Register Addressing
Both of these DUARTs contain registers that can be read from or written to. Each of
these registers can be accessed by specifying its address via the 4 Address Bit Inputs. This
access of the DUART Registers via the Address Inputs is referred to as “Register
Addressing”.
The Register Addressing between these two devices are slightly difference. Please note
that some of these DUART registers are “Read Only” registers, and some are “Write
Only” registers. Therefore, the Register Addressing comparison is based on “Read Mode”
Register Access and “Write Mode” Register Access. Table 1 presents the DUART
Address and the corresponding “Read” mode registers that the will be accessed for each of
these two devices.
