CTC = 0: 40 mVrms
CTC = 1: 70 mVrms
However, the frequency ranges will be as follows when CTC is 1.
HCTR: 8 to 12 MHz, LCTR: 400 to 500 kHz
Integrating Count
Note: CTE: 0

General-purpose counter reset
General-purpose counter start
Restarts on a new 1 setting
In integrated count mode, the count value is accumulated in the general-purpose counter.
Care is required to handle counter overflow.
Counter values: 0

to FFFFF
H
(1,048,575)
To implement the integrating count operation leave CTE set to 1. When the serial data (IN1) is transmitted again, the general-purpose counter will
start to measure the input again and the result will be added to the count.
