Temporary register
[Legend]
(1) No data is transferred from the buffer register to the temporary register in the buffer transfer-disabled period
(2) Data is transferred from the temporary register to the general register even in the buffer transfer-disabled period.
(3) After buffer transfer is enabled, data is transferred from the buffer register to the temporary register.
Note: * When buffer transfer at the crest is selected.
General register
(bits BTE1 and BTE0 in TBTER are set to 0 and 1, respectively).
