(a) Function as compare register
(b) Function as capture register
The following table shows the functions of the capture/compare register in each mode, and how to write data to
the compare register.
Notes 1. In the V850E/IF3, this mode is only for TAA2 and TAA4. In the V850E/IG3, this mode is only for
Remark
The TAAnCCR1 register can be rewritten even when the TAAnCTL0.TAAnCE bit = 1.
The set value of the TAAnCCR1 register is transferred to the CCR1 buffer register. When the value of the
16-bit counter matches the value of the CCR1 buffer register, a compare match interrupt request signal
(INTTAnCC1) is generated. If TOAm1 pin output is enabled at this time, the output of the TOAm1 pin is
inverted.
The compare register is not cleared by setting the TAAnCTL0.TAAnCE bit to 0.
When the TAAmCCR1 register is used as a capture register in the free-running timer mode, the count
value of the 16-bit counter is stored in the TAAmCCR1 register if the valid edge of the capture trigger input
pin (TIAm1 pin) is detected. In the pulse-width measurement mode, the count value of the 16-bit counter
is stored in the TAAmCCR1 register and the 16-bit counter is cleared (0000H) if the valid edge of the
capture trigger input pin (TIAm1 pin) is detected.
Even if the capture operation and reading the TAAmCCR1 register conflict, the correct value of the
TAAmCCR1 register can be read.
The capture register is cleared by setting the TAAmCTL0.TAAmCE bit to 0.
Remark
2. Writing to the TAAmCCR1 register is the trigger.
