1. The MR1 to MR0 bits selects the following measurements.
2. The MR3 bit is indeterminate when reset.
3. The CNT3 to CNT0 bits in the TCSPR register select no division (n=0) or divide-by-2n (n=1 to 15).

When the timer overflows, the MR3 bit is set to "1" (overflow) simultaneously. When the TBiS bit is
set to "1" (start counting) and the next count source is counted after the MR3 bit is set to "1", the
MR3 bit is set to "0" (no overflow) by writing again.
The MR3 bit cannot be set to "1" by program.
