(3) Operation by external event count input (EVTBn)
External event count input
(a) Operation
TABnCCR0 register
TABnCCR1 register
TABnCCR2 register
TABnCCR3 register
To count the 16-bit counter at the valid edge of the external event count input (EVTBn) in the interval timer
mode, the 16-bit counter is cleared from FFFFH to 0000H by the valid edge of the external event count
input after the TABnCE bit is set from 0 to 1.
When 0001H is set to both the TABnCCR0 and TABnCCRb registers, the output of the TOBn0 and TOBnb
pins is inverted each time the 16-bit counter counts twice (b = 1 to 3).
The TABnCTL1.TABnEEE bit can be set to 1 in the interval timer mode only when the timer output (TOBn0,
TOBnb) is used with the external event count input.
