The following types of contention or operation can occur in timer V operation.
1. Writing to registers is performed in the T3 state of a TCNTV write cycle. If a TCNTV clear
2. If a compare match is generated in the T3 state of a TCORA or TCORB write cycle, the write
3. If compare matches A and B occur simultaneously, any conflict between the output selections

clock sources. When TCNTV is internally clocked, an increment pulse is generated from the
falling edge of an internal clock signal, that is divided system clock (φ). Therefore, as shown
in figure 11.3 the switch is from a high clock signal to a low clock signal, the switchover is
seen as a falling edge, causing TCNTV to increment. TCNTV can also be incremented by a
switch between internal and external clocks.
