(1)| ro first byte is wo
| Looping queue register
Writing to first byte resets the queue position to the nth element
| Writing to this register pushes values on top of register 0x60's stack. Reading from this register doesn't advance the stack.
The first byte is used to store flags for managing FIRM/NS state - bit0 = "WirelessDisabled", bit1 = "SoftwareClosed", bit2 = "PowerOffInitiated", bit4 = "LegacyJumpProhibited". This register survives power-off, but
does not seem to be saved to non-volatile storage (does not survive battery pulls ). This register doesn't seem to actually control MCU behaviour by itself, it just seems to be used for storing arbitrary data.
