MC9S12HY64 Datasheet, PDF (51/792 Pages) Freescale Semiconductor, Inc – S12 Microcontrollers

Device Overview MC9S12HY/HA-Family
Consult the ATD section for information about the analog-to-digital converter module. References to
freeze mode are equivalent to active BDM mode.
1.14 S12CPMU Configuration
The bandgap reference voltage V_BG and the output voltage of the temperature sensor V_HT can be
connected to the ATD channel SPECIAL17 (see Table 8-15.) using the VSEL (Voltage Access Select Bit)
in CPMUHTCTL register (see Table 7-13.)
1.15 Documentation Note
The terms S12P, S12X and S12S which appear in some of the following chapters refer to the original
architecture which those modules were designed to work with. Please do not confuse them with the
S12HY/S12HA product families.
S12HY/S12HA will support only 10-bit ATD resolution, although in ATD12B8C block it still has the 12-
bit descriptions.
