TMTn counter write buffer register (TTnTCW)
The TTnTCW register is a write buffer register that can write the counter value.
The setting value is valid only in the encoder compare mode, encoder capture mode. In all other
modes, the setting value is invalid.
This register can be read and written in 16-bit units.
Reset input clears this register to 0000H.
Remark:
When TTnECC of register TTnCTL2 = 0, the setting value is loaded to the counter when the
TTnCE bit is set (to 1). (When TTnECC = 1, the counter holds its value, so it is not
reloaded.)

TMTn counter read buffer register (TTnCNT)
The TTnCNT register is a read buffer register that can read the counter value.
This register can be read in 16-bit units only.
Reset input clears this register to 0000H.
Remark:
When, in the encoder compare mode, encoder capture mode, the value of the TTnCE bit is
changed from “1” to “0”, the value that can be read by the TTnCNT register differs according
to the following conditions.
•
When bit TTnECC of the TTnCTL2 register = 0, 0000H can be read.
•
When bit TTnECC = 1, the value held when bit TTnCE was cleared to "0" can be read.
