79RC32438 User Reference Manual

November 4, 2002

The ADDR, DBAnDBA, DBMnDBM, DATA, and DBVnDBV fields are 32 bits wide for 32-bit processors

and 64 bits wide for 64-bit processors. The BYTELANE, DBCnBLM, and DBCnBAI fields are four bits wide

for 32-bit processors and eight bits wide for 64-bit processors. The width is indicated as “N” in the equations

below. The match equations are shown below with “C”-like operators. In the equation, 0 means all bits are

0’s, and ~0 means all bits are 1’s. The bit widths are similar to the widths of the parameters. DB_match is

the overall match equation (the DB_addr_match, DB_no_value_compare, and DB_value_match equations

in the DB_match equation are defined below):

( ( ( TYPE = = load ) && ! DBCn

) || ( ( TYPE = = store ) && ! DBCn

DB_addr_match && ( DB_no_value_compare || DB_value_match )

DB_addr_match is defined as:

DB_addr_match =

|| ( ASID = = DBASIDn

| ~ ( ADDR ^ DBAn

) ) = = ~0 ) &&

& BYTELANE ) != 0 )

The DB_addr_match equation also applies to 64-bit processors running in 32-bit addressing mode, in

which case all 64 bits are compared between the ADDR and the DBAn

DB_no_value_compare is defined as:

DB_no_value_compare =

| ~ BYTELANE ) = = ~0 )

If a data value compare is indicated on a breakpoint, then DB_no_value_compare is false, and if there is

no data value compare then DB_no_value_compare is true. Note that a data value compare is a run-time

property of the breakpoint if (DBCn

) is not ~0, because DB_no_value_compare then

depends on BYTELANE provided by the load/store instructions.

If a data value compare is required, then the data value from the data bus is compared and masked with

the registers for the data breakpoint, as shown in the DB_value_match equation:

DB_value_match =

( ( DATA[7:0] = = DBVn

) || ! BYTELANE[0] || DBCn

( ( DATA[15:8] = = DBVn

) || ! BYTELANE[1] || DBCn

( ( DATA[8*N-1:8*N-8] = = DBVn

DBV[8*N-1:8*N-8]

! BYTELANE[N-1] || DBCn

Data value from the data bus.

32 / 64 bits

Conditional Data breakpoint n data value for com-

32 / 64 bits

Conditional Byte lane mask for value compare on

data breakpoint. BLM[0] masks byte at bits [7:0] of

the data bus, BLM[1] masks byte at bits [15:8], etc.:

0: Compare corresponding byte lane

1: Mask corresponding byte lane
