Analog Comparator (S08ACMPV3)
9.1
The analog comparator module (ACMP) provides a circuit for comparing two analog input voltages or for
comparing one analog input voltage to an internal reference voltage. The comparator circuit is designed to
operate across the full range of the supply voltage (rail-to-rail operation).
All MC9S08DZ60 Series MCUs have two full function ACMPs in a 64-pin package. MCUs in the 48-pin
package have two ACMPs, but the output of ACMP2 is not accessible. MCUs in the 32-pin package
contain one full function ACMP.
9.1.1
When using the bandgap reference voltage for input to ACMP+, the user must enable the bandgap buffer
by setting BGBE =1 in SPMSC1 see

(SPMSC1).” For value of bandgap voltage reference see
Introduction
ACMP Configuration Information
MC9S08DZ60 Series devices operate at a higher voltage range (2.7 V to
5.5 V) and do not include stop1 mode. Please ignore references to stop1.
