ferred from the capture buffer to the capture register. If a trigger input does not appear within a
period, the data captured in the previous period remains in the capture buffer and is transferred to the
capture register at the end of the period. If more than one trigger edge is detected within a period, the
data captured last is written to the capture register.
upper byte of capture register A (TC7CAPAH), lower byte of capture register B (TC7CAPBL), and
upper byte of capture register B (TC7CAPBH). Note that reading only the rising-edge captured data
(TC7CAPA) does not update the next captured data. The falling-edge captured data (TC7CAPB)
must also be read.
causes the capture registers to enter protected state, in which captured data cannot be updated. Read-
ing a value from the upper byte of the TC7CAPB cancels that state, re-enabling the updating of cap-
tured data (The TC7CAPA and TC7CAPB are read as a single set of operation).
a dummy read of capture registers is performed in the first period to cancel the protected state.
within a period. Captured data is updated (An edge is detected) only when the timer is operating
(TC7ST = 1). If a timer stop command (TC7ST = 0) is written within a period, captured data will be
undefined. Captured data is not updated after a one-time stop command is written. In one-time stop
mode, no trigger is accepted after a STOP command is given.
The captured data is first stored in the capture buffer. At the end of the period, the data is trans-
Captured data must be read in the following order: Lower byte of capture register A (TC7CAPAL),
