3.7.1 Individual Functions CloseTimer1 CloseTimer2 CloseTimer3 CloseTimer4 CloseTimer5 Description: This function turns off the 16-bit timer module. Include: timer.h Prototype: void CloseTimer1(void); void CloseTimer2(void); void CloseTimer3(void); void CloseTimer4(void); void CloseTimer5(void); Arguments: None Return Value: None Remarks: This function first disables the 16-bit timer interrupt and then turns off the timer module. The Interrupt Flag bit (TxIF) is also cleared. Source File: CloseTimer1.c CloseTimer2.c CloseTimer3.c CloseTimer4.c CloseTimer5.c Code Example: CloseTimer1(); CloseTimer23 CloseTimer45 Description: This function turns off the 32-bit timer module. Include: timer.h Prototype: void CloseTimer23 (void) void CloseTimer45 (void) Arguments: None Return Value: None Remarks: This function disables the 32-bit timer interrupt and then turns off the timer module.The Interrupt Flagbit (TxIF) is also cleared. CloseTimer23turns off Timer2 and disables Timer3 Interrupt. CloseTimer45turns off Timer4 and disables Timer5 Interrupt. Source File: CloseTimer23.c CloseTimer45.c Code Example: CloseTimer23(); ConfigIntTimer45 Mô tả: Chức năng này cấu hình 32-bit giờ gián đoạn.
