ZBasic Microcontrollers
For native mode devices, the ISRs noted in the table below are automatically included. The notation
INT# in that table indicates the default or specified zero-crossing interrupt input, e.g. INT0, INT1, etc.
The timing for the X-10 signaling is derived from the RTC timer using a second output compare register
(OCRnB). Target devices that do not have a second compare register consequently do not support the
low-level X-10 functionality. Further, an application must include the RTC functionality (present by default
in ZX devices, not so in generic target devices) in order to support the low-level X-10 functionality.

Compatibility
If the RTC is not enabled in your application or if the target device does not have a second output
compare register on the RTC timer, this routine will not be available. Moreover, it is not available in
BasicX compatibility mode.
