cfg_wr
The cfg_wr command performs single-cycle PCI configuration write
transactions with the address, data, and byte enable provided in the
command arguments.
mem_wr_32
The mem_wr_32 command performs a memory write with the address
and data provided in the command arguments. This command can
perform a single-cycle or burst 32-bit memory write depending on the
number of DWORDs provided in the command argument.
■ The mem_wr_32 command performs a single-cycle 32-bit memory
write if the DWORD value is 1.
■ The mem_wr_32 command performs a burst-cycle 32-bit memory
write if the DWORD value is greater than 1. In a burst transaction, the
first data phase uses the data value provided in the command. The
subsequent data phases use values incremented sequentially by 1
from the data provided in the command argument.
Syntax: cfg_wr(address, data, byte_enable)
Arguments: address Transaction address. This value must be in
hexadecimal radix.
data Transaction data. The data must be in
hexadecimal radix.
byte_enable Transaction byte enable. The byte enable
value must be in hexadecimal radix
Syntax: mem_wr_32(address, data, dword)
Arguments: address Transaction address. This value must be in
hexadecimal radix.
data Data used for the first data phase. Subsequent
data phases use a value incremented sequentially
by 1. This value must be in hexadecimal radix.
dword The number of DWORD s written during the
transaction. A value of 1 indicates a single-cycle
memory write transaction. A value greater than one
indicates a burst transaction. This value must be an
integer.
