Microcomputer having function to specify functional block having data to be monitored and to output data as an anaglog signal

摘要

A microcomputer includes addressable functional blocks and an internal state latch coupling an A/D converter to an internal bus. A programmable selector is coupled to the address bus and controls the latch to latch data when a selected address is generated on the address bus to that the latched data is provided as an external analog signal for monitoring.
