11.3.3
TCM Cycle Lower Limit Register (TCMMINCM)
TCMMINCM is a 16-bit readable/writable register. TCMMINCM is available as a cycle lower
limit register when the TCMMDS bit in TCMCR is set to 1 (operation is in cycle measurement
mode).
In cycle measurement mode, a value that sets a lower limit on the measurement period can be set
in TCMMINCM. When the second edge (selectable with the IEDG bit in TCMCR) of the
measurement period is detected, the value in TCMCNT is transferred to TCMICR. At this time,
the values in TCMICR and TCMMINCM are compared. The MINUDF flag in TCMCSR is set to
1 if the value in TCMICR is smaller than that in TCMMINCM. TCMMLCM should always be
accessed in 16-bit units and cannot be accessed in 8-bit units. TCMMINCM is initialized to
H'0000.
11.3.4
TCM Input Capture Register (TCMICR)
TCMICR is a 16-bit read-only register. In timer mode, the value in TCMCNT is transferred to
TCMICR on the edge selected by the IEDG bit in TCMCR. At the same time, the ICPF flag in
TCMCSR is set to 1. In cycle measurement mode, the value in TCMCNT is transferred to
TCMICR on detection of the second edge of the measurement period. At this time, the ICPF flag
in TCMCSR is set to 1. TCMICR should always be accessed in 16-bit units and cannot be
accessed in 8-bit units. TCMICR is initialized to H'0000.
11.3.5
TCM Input Capture Buffer Register (TCMICRF)
TCMICRF is a 16-bit read only register. TCMICRF can be used as TCMICR buffer register.
When input capture is generated, the value in TCMICR is transferred to TCMICRF.
TCMICR and TCMICRF should always be accessed in 16-bit units and cannot be accessed in 8-
bit units. TCMICRF is initialized to H'0000.
