Section 7 Analog to Digital Converter (ATD) Block
Description
Consult the ATD_10B16C Block Guide for further information about the A/D Converter module for the
MC9S12KG128(64)(32), MC9S12KL128(64) and MC9S12KC128(64). When the ATD_10B16C Block
Guide refers to freeze mode this is equivalent to active BDM mode.
Consult the ATD_10B8C Block Guide for further information about the A/D Converter module for the
MC9S12KT256 and MC9S12KG256. When the ATD_10B8C Block Guide refers to freeze mode this is
equivalent to active BDM mode.
Section 8 Clock Reset Generator (CRG) Block Description
Consult the CRG Block Guide for information about the Clock and Reset Generator module.
8.1 Device-specific information
The Low Voltage Reset feature uses the low voltage reset signal from the VREG module as an input to the
CRG module. When the regulator output voltage supply to the internal chip logic falls below a specified
threshold the LVR signal from the VREG module causes the CRG module to generate a reset. Consult the
VREG Block Guide for voltage level specifications.
