The dedicated Dead Time prescaler in front of the Dead Time Generator can divide the
Timer/Counter1 clock (PCK or CK) by 1, 2, 4 or 8 providing a large range of dead times that can
be generated. The Dead Time prescaler is controlled by two bits DTPS11 and DTPS10 from the
Dead Time Prescaler register. These bits define the division factor of the Dead Time prescaler.
The division factors are given in
Table 12-16. Division factors of the Dead Time prescaler
• Bits 3:0 – CS13, CS12, CS11, CS10: Clock Select Bits 3, 2, 1, and 0
The Clock Select bits 3, 2, 1, and 0 define the prescaling source of Timer/Counter1.
Table 12-17. Timer/Counter1 Prescaler Select
The Stop condition provides a Timer Enable/Disable function.
