Can someone point me to a datasheet on RFSYS or RFVBAT peripheral in Kinetis devices?
I know RFVBAT is a register file in VBAT domain. But I have no clue about RFSYS - except that it is also a group of registers. The K22, K60, K81 mcu header files have definitions for these peripherals. But the datasheet or the reference manuals do not have a word about them.
Is there a separate manual for these peripherals or am I missing something?
