11.2.2 16-bit capture mode
It uses an internal/external clock as a clock source. Basically, the 16-bit timer 1 capture mode has the
same function as the 16-bit timer/counter mode, and the interrupt occurs when T1CNTH/T1CNTL is
equal to T1ADRH/T1ADRL. The T1CNTH, T1CNTL values are automatically cleared by a match
signal. It can be cleared by software (T1CC) too.
A timer interrupt in capture mode is very useful when the pulse width of captured signal is wider than
the maximum period of timer. Capture result is loaded into T1BDRH/T1BDRL.
According to EIPOL1 registers setting, the external interrupt EINT11 function is selected. EINT11 pin
must be set as an input port.
