Modes of Operation
The MCU can operate in different modes. These are described in
1.9.1 Chip Configuration Modes
The MCU can operate in different power modes to facilitate power saving when full system performance
is not required. These are described in
.
Some modules feature a software programmable option to freeze the module status whilst the background
debug module is active to facilitate debugging. This is referred to as freeze mode at module level.
1.9.1
Chip Configuration Modes
The different modes and the security state of the MCU affect the debug features (enabled or disabled).
The operating mode out of reset is determined by the state of the MODC signal during reset (
).
The MODC bit in the MODE register shows the current operating mode and provides limited mode
switching during operation. The state of the MODC signal is latched into this bit on the rising edge of
RESET
1.9.1.1
Normal Single-Chip Mode
This mode is intended for normal device operation. The opcode from the on-chip memory is being
executed after reset (requires the reset vector to be programmed correctly). The processor program is
executed from internal memory.
