Bit 6—Reset Output Enable (RSTOE): Enables or disables external output at the RESO pin of
the reset signal generated if TCNT overflows during watchdog timer operation.
Bits 5 to 0—Reserved: Read-only bits, always read as 1.
12.2.4
The watchdog timer’s TCNT, TCSR, and RSTCSR registers differ from other registers in being
more difficult to write. The procedures for writing and reading these registers are given below.
Writing to TCNT and TCSR: These registers must be written by a word transfer instruction.
They cannot be written by byte instructions. Figure 12.2 shows the format of data written to
TCNT and TCSR. 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 contain H'5A (password for
TCNT) or H'A5 (password for TCSR). This transfers the write data from the lower byte to TCNT
or TCSR.
