CHAPTER 7 16-BIT TIMER/EVENT COUNTER AB (TAB)
(b) Batch write
In this mode, data is transferred all at once from the TABnCCR0 to TABnCCR3 registers to the CCR0 to
CCR3 buffer registers during timer operation. This data is transferred upon a match between the value of
the CCR0 buffer register and the value of the 16-bit counter. Transfer is enabled by writing to the
TABnCCR1 register.
Whether to enable or disable the next transfer timing is controlled by writing or not writing to the
TABnCCR1 register.
In order for the set value when the TABnCCR0 to TABnCCR3 registers are rewritten to become the 16-bit
counter comparison value (in other words, in order for this value to be transferred to the CCR0 to CCR3
buffer registers), it is necessary to rewrite TABnCCR0 and finally write to the TABnCCR1 register before
the 16-bit counter value and the CCR0 buffer register value match. The values of the TABnCCR0 to
TABnCCR3 registers are transferred to the CCR0 to CCR3 buffer registers upon a match between the
count value of the 16-bit counter and the value of the CCR0 buffer register. Thus, even when wishing only
to rewrite the value of the TABnCCR0, TABnCCR2, or TABnCCR3 register, also write the same value
(same as preset value of the TABnCCR1 register) to the TABnCCR1 register.
