Page 217 of 346 Start Back Next End ZBasic System Library 205 ZBasic Microcontrollers (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.
