(4) Time Difference Measurement
The 16-bit up-counter (UC0) is programmed to operate as a free-running counter. The UC0 value
is latched into Capture Register 0 (TB0CP0) on the rising edge of TB0IN0. The TB0IN0 pin is
shared with INT5; the Interrupt Controller (INTC) is to be programmed to generate the INT5
interrupt at this time.
The TB0IN1 pin is shared with INT6; the INTC is to be programmed to generate the INT6
interrupt at this time.
calculated by multiplying the counter clock period by the difference between the TB0CP1 and
TB0CP0 values.
The capture function can be used to measure the time difference between two event occurrences.
Then, the UC0 value is latched into Capture Register 1 (TB0CP1) on the rising edge of TB0IN1.
The time difference between the two events that occurred on the TB0IN0 and TB0IN1 pins is
