Rev. 0 | Page 11 of 24
The Registers MAP button, when clicked, activates another
method to read and write the ADP5020 registers, as shown in
Figure 19.
The register values, previously set, are transferred into the Register
MAP window. You ha ve the choice to modify the registers bitwise
by clicking the desired bit position. The bit value then switches
from 0 to 1, or vice versa. It is not possible to change the values
for the grayed bits. The register values can also be changed by
entering a hexadecimal value in the text box for the respective
register (for example, 4C is entered for Register 0x00 in Figure 19).
The Hex/Dec button allows you to change the data format of
the register values from hexadecimal to decimal, or vice versa.
Binary and Byte controls are intercommunicating; therefore,
changes to one control are automatically reflected in the other.
The R and W buttons next to each register allow reading or writing
a specific device address, and the Read ALL and Wr ite ALL
buttons allows you to read or write the entire register map from
or to the ADP5020 under evaluation. The OK/Fail indicator
next to these two buttons shows the operation result. Click EXIT
to return in the main window. The modified registers are then
transferred automatically into the USER REGISTER section of
the GUI window.
The register map utility does not have the Smart Update
option; therefore, a new value is written into the ADP5020
following a write operation (by clicking the W or Write ALL
buttons).
REGISTER COMMAND OPTIONS
The Regs Refresh check box, when selected, enables the
program to read the device statuses periodically. The refresh
time is programmable in the Refresh Rate box from 100 ms to
10 sec. The registers read during the refresh are Register 0x00, the
revision register, Register 0x03 (BK1_PGOOD, BK2_PGOOD,
and LDO_PGOOD), and Register 0x04 (TSD), providing a real-
time indication of the device functionality. If a thermal shutdown
event is detected, you must disable the register refresh option
(clear the Regs Refresh check box) to clear the TSD flag. The
Access blue indicator, when lit up, indicates that the refresh
operation is taking place.
The Smart Update check box, when selected, enables the pro-
gram to automatically write an ADP5020 register when a USER
REGISTER option has been changed. This avoids the need to click
the Write Registers button every time a value is changed. The
Smart Update check box must be cleared if you want to control the
write operations.
