(2) Batch rewrite mode (transfer mode)
This mode is specified by setting the TABnOPT0.TABnCMS bit to 0, the TABnOPT1.TABnID4 to
TABnOPT1.TABnID0 bits to 00000, and the TABnOPT2.TABnRDE bit to 0.
In this mode, the values written to each compare register are transferred to the internal buffer register all at
once at the transfer timing and compared with the count value.
(a) Rewriting procedure
If data is written to the TABnCCR1 register, the values set to the TABnCCR0 to TABnCCR3, TABnOPT1,
TAAnCCR0, and TAAnCCR1 registers are transferred all at once to the internal buffer register at the next
transfer timing. Therefore, write to the TABnCCR1 register last. Writing to the register is prohibited after
the TABnCCR1 register has been written and before the transfer timing is generated (until the crest (match
between the 16-bit counter value and TABnCCR0 register value) or the valley (match between the 16-bit
counter value and 0001H)). The operation procedure is as follows.
<1> Rewriting the TABnCCR0, TABnCCR2, TABnCCR3, TABnOPT1, TAAnCCR0, and TAAnCCR1
<2> Rewriting the TABnCCR1 register.
<3> Holding the next rewriting pending until the transfer timing is generated.
<4> Return to <1>.
registers.
Do not rewrite registers that do not have to be rewritten.
Rewrite the same value to the register even when it is not necessary to rewrite the TABnCCR1
register.
Rewrite the register next time after the INTTBnOV or INTTBnCC0 interrupt has occurred.
