(3) Intermittent batch rewriting mode (transfer culling mode)
This mode is specified by setting the TABnOPT0.TABnCMS bit is 0 and the TABnOPT2.TABnRDE bit is 1.
In this mode, the values written to each compare register are transferred to the internal buffer register all at
once at the culled transfer timing and compared with the count value.
The transfer timing is the timing at which an interrupt is generated (INTTBnCC0, INTTBnOV) by interrupt
culling.
For details of the interrupt culling function, see 10.4.3 Interrupt culling function.
(a) Rewriting procedure
If data is written to the TABnCCR1 register, 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 until the transfer timing is generated (until the INTTBnOV or INTTBnCC0
interrupt occurs). The operation procedure is as follows.
<1> Rewrite the TABnCCR0, TABnCCR2, TABnCCR3, TABnOPT1, TAAnCCR0, and TAAnCCR1 registers.
<2> Rewrite the TABnCCR1 register.
<3> Hold the next rewriting pending until the transfer timing is generated.
<4> Return to <1>.
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.
Perform the next rewrite after the INTTBnOV or INTTBnCC0 interrupt has occurred.
