out pins, x ; (seems like this is not possible?)

'MOV EXEC has the same behaviour as OUT EXEC (Section 11.4.5), and allows register contents to be executed as an instruction. The MOV itself executes in 1 cycle, and the instruction in Source on the next cycle. Delay cycles on MOV EXEC are ignored, but the executee may insert delay cycles as normal.'

Registers starting from RXF0_PUTGET0 expose each RX FIFO’s internal storage registers for random read or write
access from the system,
◦ The new FJOIN_RX_PUT FIFO join mode enables random writes from the state machine, and random reads from
the system (for implementing status registers).
◦ The new FJOIN_RX_GET FIFO join mode enables random reads from the state machine, and random writes from
the system (for implementing control registers).
◦ Setting both FJOIN_RX_PUT and FJOIN_RX_GET enables random read and write access from the state machine, but
disables system access.
