This chapter addresses issues discovered by our internal testing organization that may affect the
implementation of the fido1100. This information should be used in conjunction with The
fido1100 User Guide and The fido1100 Instruction Set Reference Guide to circumvent problems
during the design process and is not intended as a standalone design guide. Although
fido1100-specific terms are clearly described, in the interest of conciseness, many terms already
familiar to designers and developers are left undefined.

Summary
Detail
Scanning mode is controlled by ADC Control Register Bit 6 (SCAN).
ADC Control Register Bit 4 (CD-Conversion Done) will correctly indicate that
conversion(s) are done.
ADC Start Register Bit 0 (START) does not self clear when non-scanning
mode conversion for single channel or multi-channel is selected.
Fatal fault recovery sequence can be disturbed by interrupts.
The vectors are reversed when a trapx instruction is executed coincident
with an interrupt to a higher priority context.
When using the RDY_N signal to insert wait states (chip select timing
register RDY_ENABLE bit = 1), the Address bus timing is incorrect.
ADC Start Register Bit 0 (START) does not self clear when non-scanning mode
