(c) Counter load function for TTnCCR0 register setting value upon underflow (bit TTnLDE
of register TTnCTL2))
The setting value of the TTnCCR0 register can be loaded to the counter upon counter underflow,
by setting TTnLDE = 1.
Bit TTnLDE is only valid in the encoder compare mode.
Count operation between 0000H and setting value of TTnCCR0 register setting
Set TTnLDE = 1, TTnECM1, 0 = 01B and perform count operation. When TTnECM0 = 1, the
counter is cleared to 0000H if the next count following a match between the counter and TTnCCR0
register is up count.
When TTnLDE = 1, the setting value of the TTnCCR0 register is loaded to the counter upon
underflow.
Therefore, the setting value of the TTnCCR0 register is used as the maximum count value and
count operation can be realized within 0000H-TTnCCR0 register setting values.
