IEDG2 - Input Edge 2
Value of the input edge determines which level transition on TCAP2 pin will
trigger a free running counter transfer to the input capture register. Reset does
not affect the IEDG2 bit.
1 =
positive edge
0 =
negative edge
IEDG1 - Input Edge
Value of the input edge determines which level transition on TCAP1 pin will
trigger a free running counter transfer to the input capture register. Reset does
not affect the IEDG1 bit.
1 =
positive edge
0 =
negative edge
8.1.5 Timer Status Register (TSR)
The timer status register is a read-only register and is illustrated below followed by
a denition of each bit. Refer to timing diagrams shown in Figure 8-3, Figure 8-2
and Figure 8-4 for timing relationship to the timer status register bits.
