1.9 System Clock Description
For the system clock description please refer to chapter Chapter 1, “Device Overview MC9S12G-Family”.
1.10 Modes of Operation
The MCU can operate in different modes. These are described in 1.10.1 Chip Configuration Summary.
The MCU can operate in different power modes to facilitate power saving when full system performance
is not required. These are described in 1.10.2 Low Power Operation.
Some modules feature a software programmable option to freeze the module status whilst the background
debug module is active to facilitate debugging.
1.10.1 Chip Configuration Summary
The different modes and the security state of the MCU affect the debug features (enabled or disabled).
