12.2.7
Only bit 1 is described here. For details on functions not related to the 8-bit timers, see sections
3.2.2 and 5.2.1, System Control Register (SYSCR), and the descriptions of the relevant modules.
Bit 1—Host Interface Enable (HIE): Controls CPU access to 8-bit timer (channel X and Y) data
registers and control registers, and timer connection control registers.
12.2.8
TCONRS is an 8-bit readable/writable register that controls access to the TMRX and TMRY
registers and timer connection operation.
TCONRS is initialized to H'00 by a reset and in hardware standby mode.
