9、How to prevent FIFO overflow
In sending or receiving data packets, in order to prevent spillage, FIFO can be set up by
reg0x24 register the corresponding threshold, more than the threshold, the chip will give
instructions, the indicator can be reg0x12 [13] FLAG (FIFO) to read.
10 、 Instructions for improving the working
reliability of the chip
In order to improve the reliability of the chip and the product yield, the following improvements
are recommended: 1. The optimized value of the 0x0a register is configured as 0x2403;
2. Before each start of sending and receiving, register 0x07 as 0x3f11 and then as 0x7f11 to
ensure that the VCO works in the best band every time it receives or sends.
Example:
write reg[0x07] = 0x3f11; write reg[0x07] = 0x7f11;
write reg[0x00] = 0x80XX(TX) or write reg[0x00] = 0x40XX(RX) [XX is the channel number]
