5-V Analog Comparator (S08ACMPV2)
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 MC9S08EL32 Series and MC9S08SL16 Series MCUs contain at least one ACMP. MC9S08EL32 and
MC9S08EL16 contain two ACMPs in the 28-pin package. See
9.1.1
When using the bandgap reference voltage for input to ACMPx+, the user must enable the bandgap buffer
by setting BGBE =1 in SPMSC1 see
Register
9.1.2
The ACMP1 module can be configured to connect the output of the analog comparator to TPM1 input
capture channel 0 by setting ACIC in SOPT2. With ACIC set, the TPM1CH0 pin is not available externally
regardless of the configuration of the TPM1 module for channel 0.
