APPLICATION INFORMATION
TIME MEASUREMENT SUPPORT
The ADATE207 contains support for time measurement
through an external time measurement unit (TMU) in the
following ways:
• Connect the high comparator output of any channel to
TMU arm, TMU start, or TMU stop.
• Connect the low comparator output of any channel to
TMU arm, TMU start, or TMU stop.
• Tristate the TMU multiplexer outputs using an enable
control bit.
The time measurement unit select logic provides time and
frequency measurement capability from any digital pin high or
low comparator output. To accomplish this task, independent
multiplexers are employed for directing the high or low
comparator outputs of the digital pins to the (three) time
measurement unit signals, TMU_ARM, TMU_START, and
TMU_STOP. Off-chip control logic must select the appropriate
TMU bus output signal from the ADATE207 devices on the
board and direct its selection to the TMU.
