Chapter 19 Enhanced Capture Timer (ECT16B8CV3)
• Four 8-bit pulse accumulators with 8-bit buffer registers associated with the four buffered IC
channels. Configurable also as two 16-bit pulse accumulators.
• 16-bit modulus down-counter with 8-bit prescaler.
• Four user-selectable delay counters for input noise immunity increase.
19.1.2 Modes of Operation
• Stop — Timer and modulus counter are off since clocks are stopped.
• Freeze — Timer and modulus counter keep on running, unless the TSFRZ bit in the TSCR1 register
is set to one.
• Wait — Counters keep on running, unless the TSWAI bit in the TSCR1 register is set to one.
• Normal — Timer and modulus counter keep on running, unless the TEN bit in the TSCR1 register
or the MCEN bit in the MCCTL register are cleared.
