TCNT and TCSR both have the same write address. The write data must be contained in the lower
byte of the written word. The upper byte must be H'5A (for TCNT) or H'A5 (for TCSR) (figure
11.6). This transfers the write data from the lower byte to TCNT or TCSR.
Writing to RSTCSR: RSTCSR must be written by a word access to address H'FFFF8612. It
cannot be written by byte transfer instructions.
Procedures for writing 0 to WOVF (bit 7) and for writing to RSTE (bit 6) and RSTS (bit 5) are
different, as shown in figure 11.7.
To write 0 to the WOVF bit, the write data must be H'A5 in the upper byte and H'00 in the lower
byte. This clears the WOVF bit to 0. The RSTE and RSTS bits are not affected. To write to the
RSTE and RSTS bits, the upper byte must be H'5A and the lower byte must be the write data. The
values of bits 6 and 5 of the lower byte are transferred to the RSTE and RSTS bits, respectively.
The WOVF bit is not affected.
