• Description: MARC4 4-bit MTP Universal Microcontroller
• Manufacturer: ATMEL [ATMEL Corporation]

3.5.4.2
4711B–4BMCU–01/05
Timer 1 Control Register (T1CR)
Table 3-16.
The T1CR is responsible for the predivision of the selected Timer 1 input clock (see TCCR). It
can be divided or used directly as clock for the up counter. Bit 0 is the mask bit for the Timer 1
interrupt.
