Non-Confidential, Unrestricted Access

B1TCADDR [22:3]

Output

CLKIN

Address for B1TCM data RAM

B1TCBYTEWR [7:0]

Output

CLKIN

Byte strobes for direct write

B1TCSEQ

Output

CLKIN

B1TCM RAM access is sequential

B1TCDATAOUT [63:0]

Output

CLKIN

Write data for B1TCM data RAM

B1TCPARITYOUT [13:0]

Output

CLKIN

Write parity or ECC code for B1TCM

B1TCACCTYPE[2:0]

Output

CLKIN

Determines access type:
b001 = Load/Store
b010 = Fetch
b100 = DMA
b100 = MBIST

c

.

a. This signal is ignored when bit [2] of the Auxiliary Control Register is set to 0, see c1, Auxiliary Control Register

on page 4-38.

b. Only generated if the processor is configured to include TCM address bus parity.
c. The MBIST interface has no way of signalling a wait. If it is accessing the TCM, and the TCM signals a wait, the

AXI slave pipeline stalls and the data arrives later. However, no signal is sent to the MBIST controller to indicate
this.
