15.2 Dependencies
15.2.1 I/O Pins
The four Timer C outputs can be directed to PC0-PC3, PD0-PD3, or PE0-PE3.
15.2.2 Clocks
The timer in Timer C is a 16-bit up-counter clocked by the peripheral clock divided by 2,
by the peripheral clock divided by 16, or by the output of timer A1 as selected in TCCR.
15.2.3 Other Registers
15.2.4 Interrupts
A Timer C interrupt is enabled in TCCR, and will occur whenever the count limit value is
reached. The interrupt request is cleared when TCCSR is read.
