在操作CC1120芯片时,将GPIO0设置成0x07, 希望当接收的数据包CRC校验ok的时候产生中断,但是测试了一下接收板根本不产生中断,如果将GPIO0配置成0x06检测同步字中断是可以的,在中断里也能检测到CRC是ok的,我用的是变长度数据包发动的。有知道的帮忙解决一下

你好,
CRC_OK:Asserted simultaneously as PKT_CRC_OK. De-asserted when the first byte is read from the RX FIFO
PKT_CRC_OK:
Asserted in RX when PKT_CFG1.CRC_CFG = 1 or 10b and a good
packet is received. This signal is always on if the radio is in TX or if the
radio is in RX and PKT_CFG1.CRC_CFG = 0. The signal is de-asserted
when RX mode is entered and PKT_CFG1.CRC_CFG ≠ 0. This signal is
also available in the LQI_VAL register
