Reading TCNT and TCSR: The read addresses are H'FFA8 for TCSR and H'FFA9 for TCNT, as
indicated in table 11.3.
These two registers are read like other registers. Byte access instructions can be used.

11.3
11.3.1
The watchdog timer function begins operating when software sets the WT/IT and TME bits to 1 in
TCSR. Thereafter, software should periodically rewrite the contents of the timer counter (normally
by writing H'00) to prevent the count from overflowing. If a program crash allows the timer count
to overflow, the entire chip is reset for 518 system clocks (518 ø), or an NMI interrupt is
requested. Figure 11.3 shows the operation.
NMI requests from the watchdog timer have the same vector as NMI requests from the NMI pin.
Avoid simultaneous handling of watchdog timer NMI requests and NMI requests from pin NMI.
A reset from the watchdog timer has the same vector as an external reset from the RES pin. The
reset source can be determined by the XRST bit in SYSCR.
