ZBasic Microcontrollers
The tables below give the set of valid pins for the InputCaptureEx subroutine and also indicate (with an
asterisk) the default pin used by the InputCapture subroutine. When an input capture operation has been
started successfully, the corresponding timer busy flag (e.g. Register.Timer1Busy) will be set True
for the duration of the input capture operation. Note that an input capture cannot be used at the same
time as an output capture operation involving the same timer.
For native code ZX devices and all generic target devices, at least two ISRs will be automatically provided
by the compiler to facilitate the input capture operation corresponding to the capture interrupt and the
timer overflow interrupt. The names of the interrupt vectors are related to the timer being used. For
example, for Timer1 the names are Timer1_Capt and Timer1_OVF. Note that if the compiler cannot
determine at compile time which timer will be used, the capture and timer overflow ISRs for all possible
timers will be included in the application.
