5.1.1.4.33 Version Number Status Register (VNSR)
Access: write
Reset value: 0x
The VNSR-register bits do not generate interrupts and are not modified by reading
VNSR. The IR and VN3…0 bits are read only bits, the SWRX-bit is a write only bit.

SACCO-A Register Description
Receive FIFO (RFIFO)
Initialization Request; this bit is set to logical 1 after an inappropriate
clocking or after a power failure. It is reset to logical 0 after a control memory
reset command: OMDR:OMS1…0 = 00, MACR = 7X.
Software Reset External.
When set, the pin RESIN is activated. RESIN is reset with the next EPIC-1
interrupt, i.e. the EPIC-1 timer may be used to generate a RESIN-pulse
without generating an internal ELIC-reset.
