This command displays a submenu with the following commands:
[0]! Crystal mode, shutdown
Bits R 15 , R 14 , and R 13 of register R are reset to 000 binary while the remaining bits are preserved
and the R register is written to the targeted board.
[1]! Crystal mode, active
Bits R 15 , R 14 , and R 13 of register R are set to 001 binary while the remaining bits are preserved and
the R register is written to the targeted board.
[2]! Reference mode, REF in enabled, REF out low
Bits R 15 , R 14 , and R 13 of register R are set to 010 binary while the remaining bits are preserved and
the R register is written to the targeted board.
[3]! Reference mode, REF out = REF in
Bits R 15 , R 14 , and R 13 of register R are set to 011 binary while the remaining bits are preserved and
the R register is written to the targeted board.
[4]! Reference mode, REF out = REF in /2
Bits R 15 , R 14 , and R 13 of register R are set to 100 binary while the remaining bits are preserved and
the R register is written to the targeted board.
[5]! Reference mode, REF out = REF in /4
Bits R 15 , R 14 , and R 13 of register R are set to 101 binary while the remaining bits are preserved and
the R register is written to the targeted board.
[6]! Reference mode, REF out = REF in /8
Bits R 15 , R 14 , and R 13 of register R are set to 110 binary while the remaining bits are preserved and
the R register is written to the targeted board.
[7]! Reference mode, REF out = REF in /16
Bits R 15 , R 14 , and R 13 of register R are set to 111 binary while the remaining bits are preserved and
