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. 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.

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.
Bits 5 and 4—Horizontal Synchronization Output Mode Select 1 and 0 (HOMOD1,
HOMOD0): These bits select the signal source and generation method for the IHO signal.
