Help: ICE_FLAGS_MUXCLK=S
IOC code allowing choice of 6 on-board clock sources
Loads IOC code allowing muxed clock operation. Both modules use the same clock.
Outputs always use MUXCLK. There 7 possible sources for the muxed clock signal:
s=N No MUXCLK
s=I Internal clock = 40MHz/N where N is an integer (1-4096)
s=A Module A input clock (or s=1)
s=B Module B input clock (or s=2)
s=C Alternate Crystal on series 3+ cards
s=D Alternate Crystal CCLK/N where N is an integer (1-64), (1-16) on series 3
s=X External clock on series 3+ cards
s=P Programmable Clock on series 4+ cards
s=PX Programmable Clock with eXternal reference (PREFX)
Many newer IO modules (especially analog modules) contain their own programmable
clocks. These clocks are not shared as the mainboard MUXCLK is.
Note: Specifying MUXCLK=PX is equivalent to MUXCLK=P with PREFX. See PREFX for details.
