RD
3.25 REGISTER DISPLAY
RD {[+|-|=][<dname>][/]}{[+|-|=][<reg1>[-<reg2>]][/]}
Use the RD command to display the target state, that is, the register state associated with the
target program (refer to the GO command). The target PC points to the instruction to be
disassembled and displayed. Internally, a register mask specifies which registers are displayed
when RD <CR> is executed. At reset time, this mask is set to display the MPU registers only.
Change this register mask with the RD command. Optional arguments allow the user the
capability to enable or disable the display of any register or group or registers. This is useful for
showing only the registers of interest, minimizing unnecessary data on the screen.
The arguments are:

-
=
