WDT0 TCSR Bit 4—Reserved Bit: A read operation on this bit always causes a 1 to be read out.
Every write operation on this bit is invalidated.
WDT1 TCSR Bit 4—Prescaler Select (PSS): This bit is used to select an input clock source for
the TCNT of WDT1.
See the descriptions of Clock Select 2 to 0 for details.

Description
Interval timer mode: WDT0 requests an interval timer interrupt (WOVI)
from the CPU when the TCNT overflows
Watchdog timer mode: A reset is issued when the TCNT overflows if the RSTE bit of
RSTCSR is set to 1 *
Description
Interval timer mode: WDT1 requests an interval timer interrupt (WOVI)
from the CPU when the TCNT overflows
Watchdog timer mode: WDT1 requests a reset or an NMI interrupt from
the CPU when the TCNT overflows
