(2) Settings in free-running timer mode (capture function)
[Initial settings]
Master timer: TAA1CTL0.TAA1CE = 0 (operation disabled)
Slave timer: TAA0CTL0.TAA0CE = 0 (operation disabled)
[Initial settings of master timer (TAA1)]
• TAA1CTL1.TAA1MD2 to TAA1CTL1.TAA1MD0 = 101 (setting of free-running timer mode)
• TAA1OPT0.TAA1CCS1 and TAA1OPT0.TAA1CCS0 = 11 (setting of capture/compare select bit to “capture”.)
• TAA1CTL1.TAA1CKS2 to TAA1CTL1.TAA1CKS0 (setting of count clock (any))
• TAA1IOC1.TAA1IS3 to TAA1IOC1.TAA1IS0 (specification of valid edge of capture trigger)
[Initial settings of slave timer (TAA0)]
• TAA0CTL1.TAA0SYE = 1 (setting of timer-tuned operation)
• TAA0CTL1.TAA0MD2 to TAA0CTL1.TAA0MD0 = 101 (setting of free-running timer mode)
• TAA0OPT0.TAA0CCS1 and TAA0OPT0.TAA0CCS0 = 11 (setting of capture/compare select bit to “capture”.)
• TAA0IOC1.TAA0IS3 to TAA0IOC1.TAA0IS0 (specification of valid edge of capture trigger)
Remark The initial settings of the master timer and slave timer may be performed in any order.
[Starting counting]
<1> Set TAA1CTL0.TAA1CE of the master timer to 1.
<2> Start counting.
[End condition]
• Set TAA1CTL0.TAA1CE of the master timer to 0.
