Function
The ENTER key lets you enter addresses, data, and baud rates in display, modify,
fill, lock, and load modes. After entering an address or data from the hexadecimal
keyboard, press the ENTER key to tell the firmware to accept the entry.
Refer to the SHIFT-ADDR 0, SHIFT-DATA 1, SHIFT-FILL 2, SHIFT-LOAD 3,
and SHIFT-LOCK 4 sections in this chapter for further information on the
ENTER key.
Function
The SHIFT key used with the ADDR 0 key lets you select an address for display.
When you press the SHIFT and ADDR 0 keys simultaneously, the following ap­
pears on the alphanumeric display:
EDIT ADDR
The least significant digit of the address field blinks to indicate the current field of
entry. Enter the most significant digit first. After entering a digit, the previously
entered digits are shifted left. The least significant digit stops blinking once the ad­
dress field is filled. Press the ENTER key to display the data at the selected address
in RAM. If you press the CLEAR key instead of the ENTER key, the address field
returns to the original address.
Any valid address entered on the hex keypad followed by the ENTER key becomes
the current address value; the data at that location in RAM is displayed. If you
press the ENTER key again without entering an address, the next sequential loca­
tion is displayed. If you hold down the ENTER key for more than 1 -lh seconds,
sequential addresses are displayed at ^-second intervals until you release the key.
If you enter an address greater than the current valid size for the selected PROM
type, the following message is flashed on the display for one second:
ADDRESS OUT OF RANGE
Then, all fields (command, address, and data) are displayed as they were prior to
entering the invalid address. Address field editing restarts at the address that was
in the address field before the erroneous entry.
