ARCHIVED BY FREESCALE SEMICONDUCTOR, INC. 2005
To access this command in the program, select a board in the "Define boards to program" screen and
then press [Q]! . This will place you in the "Select from the available options" screen. The command [R]
is on this screen.
See page 32 of this document for a sample screen shot of this command.
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
the R register is written to the targeted board.
