SetPulseOC4 SetPulseOC5 SetPulseOC6 SetPulseOC7 SetPulseOC8 Description: This function configures the Output Compare main and secondary registers (OCxR and OCxRS ) whenthe module is not in PWM mode. Include: outcompare.h Prototype: void SetPulseOC1(unsigned int pulse_start, unsigned int pulse_stop); void SetPulseOC2(unsigned int pulse_start, unsigned int pulse_stop); void SetPulseOC3(unsigned int pulse_start, u nsigned int pulse_stop); void SetPulseOC4(unsigned int pulse_start, unsigned int pulse_stop); void SetPulseOC5(unsigned int pulse_start, unsigned int pulse_stop); void SetPulseOC6(unsigned int pulse_start, unsigned int pulse_stop); void SetPulseOC7(unsigned int pulse_start, unsigned int pulse_stop); void SetPulseOC8(unsigned int pulse_start, unsigned int pulse_stop); Arguments: pulse_start This is the value to be stored into Output Compare Main register (OCxR). pulse_stop This is the value to be stored into Output Compare Secondary register (OCxRS). Return Value: None Remarks: The Output Compare duty cycle registers (OCxR and OCxRS) will be configured with new values only ifthe module is not in PWM mode.

Chức năng có thể được thực hiện như các macro. 3.12.1 Chức năng cá nhân BusyUART1 BusyUART2 Mô tả: Chức năng này trả về tình trạng truyền UART. Bao gồm: uart.h Prototype: char BusyUART1 (void); char BusyUART2 (void); Lập luận: Không Quay trở lại giá trị: Nếu "1" được trả lại, nó chỉ ra rằng UART là bận rộn trong truyền tải và UxSTA bit "0". Nếu "0" được trả lại, nó chỉ ra rằng UART là không bận rộn và UxSTA bit '1'. Bình luận: Chức năng này trả về tình trạng của UART. Điều này cho thấy nếu UART là bận rộn trong truyền như được chỉ ra bởi các UxSTA bit. Source File: BusyUART1.c BusyUART2.c Mã số Ví dụ: trong khi (BusyUART1 ()); CloseUART1 CloseUART2 Mô tả: Chức năng này sẽ tắt các mô-đun UART Bao gồm: uart.h Prototype: void CloseUART1 (void); làm mất hiệu lực CloseUART2 (void); Lập luận: Không Trở lại giá trị: Không Bình luận: Chức năng này đầu tiên sẽ tắt các module UART và sau đó vô hiệu hóa UART truyền và nhận interrupts.The Cờ ngắt bit cũng có xóa.
