4.7 Background Debugging Mode
The background debugger on the CPU32L is implemented in CPU microcode. The background debug-
ging commands are summarized in

Description
Read D/A Register
RDREG/RAREG
Read the selected address or data register and return
the results through the serial interface.
The data operand is written to the specified address or
data register.
The specified system control register is read. All regis-
ters that can be read in supervisor mode can be read in
background mode.
The operand data is written into the specified system
control register.
Read the sized data at the memory location specified
by the long-word address. The source function code
register (SFC) determines the address space access-
ed.
Write the operand data to the memory location speci-
fied by the long-word address. The destination function
code (DFC) register determines the address space ac-
cessed.
Used in conjunction with the READ command to dump
large blocks of memory. An initial READ is executed to
set up the starting address of the block and retrieve the
first result. Subsequent operands are retrieved with the
DUMP command.
Used in conjunction with the WRITE command to fill
large blocks of memory. Initially, a WRITE is executed
to set up the starting address of the block and supply
the first operand. The FILL command writes subse-
quent operands.
The pipe is flushed and refilled before resuming in-
struction execution at the current PC.
Current program counter is stacked at the location of
the current stack pointer. Instruction execution begins
at user patch code.
Asserts RESET for 512 clock cycles. The CPU is not
reset by this command. Synonymous with the CPU RE-
SET instruction.
NOP performs no operation and can be used as a null
command.
