Section 13 Timer Connection [H8S/2138 Group]
Bit 0—IVI Signal Level (IVI): Indicates the current level of the IVI signal. Signal source and
phase inversion selection for the IVI signal depends on the contents of TCONRI. Read this bit to
determine whether the input signal is positive or negative, then maintain the IVI signal at positive
phase by modifying TCONRI.

MSTPCR, comprising two 8-bit readable/writable registers, performs module stop mode control.
When the MSTP13, MSTP12, and MSTP8 bits are set to 1, the 16-bit free-running timer, 8-bit
timer channels 0 and 1, and 8-bit timer channels X and Y and timer connection, respectively, halt
and enter module stop mode. See section 24.5, Module Stop Mode, for details.
MSTPCR is initialized to H'3FFF by a reset and in hardware standby mode. It is not initialized in
software standby mode.
MSTPCRH Bit 5—Module Stop (MSTP13): Specifies FRT module stop mode.
