TCONRS is an 8-bit readable/writable register that selects 8-bit timer TMRX/TMRY access and
the synchronization signal output signal source and generation method.
TCONRS is initialized to H'00 by a reset and in hardware standby mode.
Bit 7—TMRX/TMRY Access Select (TMRX/Y): The TMRX and TMRY registers can only be
accessed when the HIE bit in SYSCR is cleared to 0. In the H8S/2148 Group, some of the TMRX
registers and the TMRY registers are assigned to the same memory space addresses (H'FFF0 to
H'FFF5), and the TMRX/Y bit determines which registers are accessed. In the H8S/2144 Group
and H8S/2147N, there is no control of TMRY register access by this bit.
Bit 7
TMRX/Y Description
0 The TMRX registers are accessed at addresses H'FFF0 to H'FFF5 (Initial value)
1 The TMRY registers are accessed at addresses H'FFF0 to H'FFF5
Bit 6—Internal Synchronization Signal Select (ISGENE): Selects internal synchronization
signals (IHG, IVG, and CL4 signals) as the signal sources for the IHO, IVO, and CLO signals.
