Function

Remote control timer overflow interrupt flag (1=indicates that an overflow has occurred;

0=indicates that an overflow has not occurred)

Real time clock interrupt flag (1=indicates that an RTC interrupt has occurred; 0=indicates

that an RTC interrupt has not occurred)

Remote control timer rising edge interrupt flag (1=indicates that a rising edge interrupt has

occurred; 0=indicates that a rising edge interrupt has not occurred)

Remote control timer falling edge interrupt flag (1=indicates that a falling edge interrupt has

occurred; 0=indicates that a falling edge interrupt has not occurred)

Controls the real time clock interrupt (1=enable; 0=disable)
