rw 0x00
rw 0x00
rw 0x00 reserved. Retain default value
rw 0x00 Allows the mapping of either Rssi Or PreambleDetect to the
DIO pins, as summarized on Table 26 and Table 27
0 → Rssi interrupt
1 → PreambleDetect interrupt
Version register
r 0x21 Version code of the chip. Bits 7-4 give the full revision number;
bits 3-0 give the metal mask revision number.
