See Variable value as Hexadecimal Values in Debug
You can use the EVAL debug command to display the value of variables in hexadecimal format. To display a variable in hexadecimal format, type:
EVAL variable-name: x 32
'32' indicates that a dump of 32 bytes after the start of the variable is to be displayed. We can change the length.
In this example, type EVAL DATA : X 1021
