To write to registers TRBPRE and TRBPR during count operation (TCSTF bit in the TRBCR register is set to
1), note the following points:
•
•
To write to registers TRBPRE and TRBPR during count operation (TCSTF bit in the TRBCR register is set to
1), note the following points:
•
•
When the TRBPRE register is written continuously during count operation (TCSTF bit is set to 1), allow three
or more cycles of the count source for each write interval.
When the TRBPR register is written continuously during count operation (TCSTF bit is set to 1), allow three
or more cycles of the prescaler underflow for each write interval.
When the TRBPRE register is written continuously, allow three or more cycles of the count source for each
write interval.
When the TRBPR register is written continuously, allow three or more cycles of the prescaler underflow for
each write interval.
