Reset_Stats() command
Reset_Stats(0x00,0x00,0x00,0x00,0x00,0x00) resets the received packet
statistics as reported in Get_Stats() (NbPktReceived, NbPktCrcError, NbPktlengthError
and NbPktHeaderError).
5.8.6 IRQ interrupt commands
There are three IRQ interrupts that can be mapped to several sub-GHz radio interrupt
sources. The source of an interrupt is determined by reading the device status. Interrupts
are cleared using Clr_IrqStatus().
There are 10 possible interrupt sources used depending on the packet type and operating
mode. Each of these interrupt sources can be enabled or masked and mapped on any of the
IRQ interrupts.
A set of commands is used to configure and control the IRQ sources and interrupt
generation
