NOTES:
b6 b5 b4
1. Bits MR1 and MR0 determine the following measurement modes:
2. The MR3 bit is undefined when reset.
3. To set the MR3 bit to 0 (no overflow), wait for one or more count source cycles to write to the TBiMR register after the MR3 bit
4. Bits CNT3 to CNT0 in the TCSPR register select no division (n = 0) or divide-by-2n (n = 1 to 15). To select f2n, set the CST bit in the
becomes 1 (overflow), while the TBiS bit in TABSR or TBSR register is set to 1 (count starts).
TCSPR register to 1 before setting bits TCK1 and TCK0 to 10b.
Pulse period measurement 1 (bits MR1 and MR0 are set to 00b):
Pulse period measurement 2 (bits MR1 and MR0 bits are set to 01b):
Pulse width measurement (bits MR1 and MR0 bits are set to 10b):
Measures the width between the falling edges of a pulse
Measures the width between the rising edges of a pulse
Measures the width between a falling edge and a rising edge of a pulse, and between a rising edge and a falling edge of a pulse
