Section 12 8-Bit Timers
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.

TICR is an 8-bit internal register to which the contents of TCNT are transferred on the falling edge
of external reset input. The CPU cannot read or write to TICR directly.
The TICR function is used in timer connection. For details, see section 13, Timer Connection.
