1.12 PROCESSOR MODES
The operation modes are described below. The memory
maps for the first three modes are shown in Figure 1.8.
Single chip mode is normally entered after reset. How-
ever, if the MCU has a CNVss pin, holding this pin high
will cause microprocessor mode to be entered after re-
set. After the reset sequence has completed, the mode
can be changed with software by modifying the value of
bits 0 and 1 of CPMA. However, while CNVss is high,
bit 1 of CPMA is “1” and cannot be changed.
