[R] Set crystal/reference mode
This command displays a submenu (screen #16) with the following commands:
[0]! Crystal mode, shutdown
Bits R15, R14, and R13 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 R15, R14, and R13 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, REFin enabled, REFout low
Bits R15, R14, and R13 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, REFout = REFin
Bits R15, R14, and R13 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, REFout = REFin/2
Bits R15, R14, and R13 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, REFout = REFin/4
Bits R15, R14, and R13 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, REFout = REFin/8
Bits R15, R14, and R13 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, REFout = REFin/16
Bits R15, R14, and R13 of register R are set to 111 binary while the remaining bits are preserved and
the R register is written to the targeted board.
[T]! Set target PLL on board
This command is only available when the targeted board is a MC145220EVK, and that board is in single
loop mode (see [B]! command). The MC145220EVK contains two PLLs, which are designated PLL and
PLL’. This command is a toggle function which directs the program to “steer” subsequent commands to
either PLL or PLL’ on the targeted MC145220EVK.
[P] Set output port address
This command prompts the user (screen #13) to input a hexadecimal address of the printer port on their
computer. This address is where the EVK boards are connected. The entered address is displayed on
screen #2 next to the [P] command prompt.
[G] Change board definitions
This command returns the user to the board definition screen. The user may then define a different cas-
cade of boards.
