QUESTION

Is the Dallas 390 supported by the Keil tools?

ANSWER

Yes. The Dallas Semiconductor 390 is compatible with the standard 8051, so it is supported by the Keil tools.

The 390 adds extra code and xdata space. You may use the code banking features of the Keil 8051 tools to access the extra code space, however, the extra xdata space is not yet directly supported. You may, however, write your own routines to access this memory.

We are working on a new compiler update that will fully support all of the additional memory (both code and xdata) that are supported by this chip. This update should be available by Summer 2000.

The new compiler will support the 390's expanded mode but not the contiguous mode. The MAC unit will also be supported.
