This LSI has two channels of capture circuits that capture the T4KHZ to T32HZ signals of the low-speed base counter
(LTBC) to the capture register at the occurrence of P00 and P01 interrupts. The circuits capture timings at which each
interrupt occurred, based on the time from the time base counter.
For the external interrupt (P00INT, P01INT) from the P00 or P01 pin, see Chapter 5, "Interrupt" and Chapter 18, "Port 0".
Figure 8-1 shows the configuration of the capture circuit.
