• Manufacturer Part Number: MC9S12G
• Description: Ignores external trigger. Performs one conversion sequence and stops.
• Manufacturer: FREESCALE [Freescale Semiconductor, Inc]

The operating mode out of reset is determined by the state of the MODC signal during reset (see
Table
mode switching during operation. The state of the MODC signal is latched into this bit on the rising edge
of RESET.
1.10.1.1
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.
1.10.1.2
This mode is used for debugging single-chip operation, boot-strapping, or security related operations. The
background debug module BDM is active in this mode. The CPU executes a monitor program located in
an on-chip ROM. BDM firmware waits for additional serial commands through the BKGD pin.
1.10.2
The MC9S12G has two static low-power modes Pseudo Stop and Stop Mode. For a detailed description
refer to S12CPMU section.
