For counter operation, pin TxIN must be configured as an input; the respective direction
control bit must be ‘0’. The maximum input frequency allowed in counter mode is
16. To ensure that a transition of the count input signal which is applied to TxIN is
recognized correctly, its level should be held for at least 8
