CC1310: CC1310 have some question about RF PHY in 4mbps 8-fsk HS mode

1. CC1310 how to know the RF recive bandwith and frequency deviation in HSM？

2.whether there have a method can change some parameter ,such as rewrite the HWREG value?

3.if there has a register list to interpret every number means in the pOverrides_hsm ?

// Overrides for CMD_RADIO_SETUP HSM
uint32_t shapeovr[] = {0x00000000, 0x00000000, 0x00000000, 0x12010000, 0x72685C43, 0x8986817A};

uint32_t pOverrides_hsm[] =
{
MCE_RFE_OVERRIDE(1,0,0,1,0,0),

ADI_REG_OVERRIDE(1,4,0x9F),
