Figure 9-51. Operation Example (Count Operation in Range from 0000H to Set Value of TT0CCR0 Register)
<3> TT0LDE bit: Transfer function of the set value of the TT0CCR0 register to the 16-bit counter when the
counter underflows
When the TT0LDE bit = 1, the set value of the TT0CCR0 register can be transferred to the 16-bit counter
when the counter underflows.
The TT0LDE bit is valid only in the encoder compare mode.
• Count operation in range from 0000H to set value of the TT0CCR0 register
Set value of TT0CCR0 register (N)
If the 16-bit counter performs a count operation when the TT0LDE bit = 1 and TT0ECM1 and TT0ECM0
bits = 01, and when the count value of the counter matches the set value of the CCR0 buffer register
when the TT0ECM0 bit = 1, the 16-bit counter is cleared to 0000H if the next count operation is
counting up.
If the 16-bit counter underflows when the TT0LDE bit = 1, the set value of the TT0CCR0 register is
transferred to the counter.
Therefore, the counter can operate in a range from 0000H to the set value of the TT0CCR0 register in
which the upper-limit count value is the set value of the TT0CCR0 register and the lower-limit value is
0000H.
