(b) Batch write
In this mode, data is transferred all at once from the TTmCCR0 and TTmCCR1 registers to the CCR0 and
CCR1 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
TTmCCR1 register. Whether to enable or disable the next transfer timing is controlled by writing or not
writing to the TTmCCR1 register.
In order for the set value when the TTmCCR0 and TTmCCR1 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 and CCR1
buffer registers), it is necessary to rewrite the TTmCCR0 register and then write to the TTmCCR1 register
before the 16-bit counter value and the CCR0 buffer register value match. Therefore, the values of the
TTmCCR0 and TTmCCR1 registers are transferred to the CCR0 and CCR1 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 TTmCCR0 register, also write the same value (same as preset
value of the TTmCCR1 register) to the TTmCCR1 register.
