Reading from the TRCSR register immediately after writing to it can result in the value previous to the write
being read out. To prevent this, execute the JMP.B instruction between the read and the write instructions.
•
Switching procedure
(1) Set the TSTART bit in the TRCMR register to 0 (count stops).
(2) Change the settings of bits TCK2 to TCK0 in the TRCCR1 register.
•
•
When the CSEL bit in the TRCCR2 register is set to 1 (count stops at compare match with the TRCGRA
register), do not set the TRCMR register at compare match timing of registers TRC and TRCGRA.
The following note applies when the CCLR bit in the TRCCR1 register is set to 1 (TRC register cleared by
compare match with TRCGRA register).
When using a program to write a value to the TRC register while the TSTART bit in the TRCMR register is
set to 1 (count starts), ensure that the write does not overlap with the timing with which the TRC register is set
to 0000h.
If the timing of the write to the TRC register and the setting of the TRC register to 0000h coincide, the write
value will not be written to the TRC register and the TRC register will be set to 0000h.
Reading from the TRC register immediately after writing to it can result in the value previous to the write
being read out. To prevent this, execute the JMP.B instruction between the read and the write instructions.
Stop the count before switching the count source.
The pulse width of the input capture signal should be set to three cycles or more of the timer RC operation
clock (refer to Table 19.1 Timer RC Operating Clocks).
The value of the TRC register is transferred to the TRCGRj register one or two cycles of the timer RC
operation clock after the input capture signal is input to the TRCIOj (j = A, B, C, or D) pin (when the digital
filter function is not used).
