Capture Data Registers H And L (Tcph And Tcpl) - Fujitsu F2MC-8L F202RA Hardware Manual

CHAPTER 8 8/16-BIT CAPTURE TIMER/COUNTER
8.4.7

Capture Data Registers H and L (TCPH and TCPL)

The capture data register H (TCPH) stores the number of events of the higher 8 bits in
the 16-bit capture mode of the 8/16-bit capture timer/counter.
The capture data register L (TCPL) stores the number of events in the 8-bit capture
mode of the 8/16-bit capture timer/counter or the number of events of the lower 8 bits in
the 16-bit capture mode.
In the read operation in the timer/counter mode, counter values are read.
■
Capture Data Registers H and L (TCPH and TCPL)
The number of events detected in the capture mode is stored in TCPH and TCPL. Data cannot be written to
these registers because the registers are read-only.
Figure 8.4-8 shows the bit structures of capture data registers H and L.
