Oscillation Pin: The BL0507 Oscillation circuit is designed for use of a 400kHz to 500kHz ceramic resonator, but there may be mutual influence between variations in the IC and the ceramic resonator resulting in abnormal oscillation. The following table shows the recommended values of C 1 and C2 when using the BL0507.The oscillation circuit starts to operate when a key is depressed.

REM Pin Output the transmission code consisting of the leader code ,custom code (16bits) and data code (16bits) .
SEL Pin DATA CODE D 7 can be controlled by this pin, allowing 128 kinds of data to be transmitted. D7 is set to “0” by connecting the pin to VDD , and to “1” by connecting the SEL pin to VSS. As the input of this pin is high-impedance, it must be connected to either VDD or Vss.
CCS Pin The custom code can be set by the diode connected to the CCS pin and the KI/O pin.
LMP Pin Outputs “L” while the REM pin is outputting a transmission code. Transmission Code The transmission code consists of a leader code, 16-bit custom code, and 8-bit data code+8-bit inverse code of the data code, they are also sent simultaneously, giving a total configuration of 32- bits per transmission. The code uses the PPM (pulse position Modulation) method, with “1” and “0” differentiated by the time between pulse. Each code consists of 8-bits, and simultaneous transmission of the inverse code allows configuration of a system with an extremely low error rate.
