• Manufacturer Part Number: h8s-2169
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2100 Series
• Manufacturer: Renesas Electronics Corporation.

Bits 7 and 6—Input Synchronization Mode Select 1 and 0 (SIMOD1, SIMOD0): These bits
select the signal source of the IHI and IVI signals.
Bit 5—Synchronization Signal Connection Enable (SCONE): Selects the signal source of the
FRT FTI input and the TMR1 TMCI1/TMRI1 input.
Bit 4—Input Capture Start Bit (ICST): The TMRX external reset input (TMRIX) is connected
to the IHI signal. TMRX has input capture registers (TICR, TICRR, and TICRF). TICRR and
TICRF can measure the width of a short pulse by means of a single capture operation under the
control of the ICST bit. When a rising edge followed by a falling edge is detected on TMRIX after
the ICST bit is set to 1, the contents of TCNT at those points are captured into TICRR and TICRF,
respectively, and the ICST bit is cleared to 0.
