5-V Analog Comparator (S08ACMPV2)
8.1
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).

8.1.1
When using the bandgap reference voltage for input to ACMP+, the user must enable the bandgap buffer
by setting BGBE =1 in SPMSC1 see
Register
8.1.2
S08ACMPV2 continues to operate in stop3 mode if enabled. If ACOPE is enabled, comparator output will
operate as in the normal operating mode and will control ACMPO pin. The MCU is brought out of stop
when a compare event occurs and ACIE is enabled; ACF flag sets accordingly.
8.1.3
The ACMP 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.
