[Z] Change default high frequency
This command prompts the user (screen #5) to input a decimal value in MHz for the default high frequen-
cy. The program default high value is displayed along with the current value. The user may leave the high
frequency value as is by entering return without a value. The program high default value is dependent on
the targeted board type (see Table 4).
This value is not sent to the board immediately. It is the value that is sent to the board when the [L] com-
mand is executed.
Table 4.

[U]! Step frequency up by step size
This command increments the NCOUNTER and ACOUNTER fields of the A register for the currently
targeted board. This steps up the PLL’s frequency by the current step size for the board.
If the currently selected board is an MC145220 in DUAL mode, then the currently targeted PLL on the
board is “stepped”. If the MC145220 is in SINGLE mode, then both PLLs on the board are “stepped”.
[D]! Step frequency down by step size
This command decrements the NCOUNTER and ACOUNTER fields of the A register for the currently
targeted board. This is the effect of stepping down the PLL’s frequency by the current step size for the
board.
If the currently selected board is an MC145220 in DUAL mode, then the currently targeted PLL on the
board is “stepped”. If the MC145220 is in SINGLE mode, then both PLLs on the board are “stepped”.
[O] Set PLL output frequency
This command prompts the user (screen #3) to input a decimal value in MHz and kHz to set the targeted
board frequency. The program default PLL output frequency is displayed along with the current value.
The user may leave the output frequency value as is by entering return without entering a value. The
program validates the entered frequency by checking to ensure that the value is a multiple of the board’s
current step size and that the entered frequency / frequency step size is
≥
4032. The program accepts
total divide values < 4032 if N
≥
A. (Total divide must be
≤
262,143 for all PLLs.)
N*P+A = total divide (p = prescale = 64 for ’191).
A further check is made to ensure that the entered frequency is within the capability of the currently tar-
geted demonstration board (see Table 5). Frequencies outside the range are allowed for users who use
their own VCO.
