(b) Batch write
In this mode, data is transferred all at once from the TAAmCCR0 and TAAmCCR1 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
TAAmCCR1 register. Whether to enable or disable the next transfer timing is controlled by writing or not
writing to the TAAmCCR1 register.
In order for the set value when the TAAmCCR0 and TAAmCCR1 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 TAAmCCR0 register and then write to the TAAmCCR1
register before the 16-bit counter value and the CCR0 buffer register value match. Therefore, the values of
the TAAmCCR0 and TAAmCCR1 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 TAAmCCR0 register, also write the same value (same as
preset value of the TAAmCCR1 register) to the TAAmCCR1 register.
