[T]! Set target PLL on board
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 [T]!
is on this screen.
See page 21 of this document for a sample screen shot of this command.
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
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 [P]
is on this screen.
See page 31 of this document for a sample screen shot of this command.
This command prompts the user 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 the main
menu next to the [P] command prompt.
[G] Change board definitions
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 [G]
is on this screen.
This command returns the user to the board definition screen. The user may then define a different cas-
cade of boards.
[I]! Initialize board(s), write all registers
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 [I] is
on this screen.
See page 21 of this document for a sample screen shot of this command.
This command writes out all of the registers for all of the boards that are currently attached to the com-
puter. The current settings are used for the registers.
This correctly writes out the C, R, and A registers for each EVK board connected to the bus. In the case
of MC145220EVKs, they are set to SINGLE (RESET/DEFAULT) mode and then have both PLL and PLL′
registers written.
[X]! Terminate demonstration program
This command is available on all screens within the program.
This command causes the program to terminate and returns the user to DOS.
