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/2138 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/2134 Group,

there is no control of TMRY register access by this bit.

Bit 7

TMRX/Y

Description

The TMRX registers are accessed at addresses H'FFF0 to H'FFF5

(Initial value)

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.
