V—Valid
6.9.4 Port E Pin Assignment Register (PEPAR)
The PEPAR controls the I/O pins associated with the EBI. Refer to Section 4 Bus Operation
for more information about the EBI. Port E pins can be independently programmed to be
either CAS3–CAS0 or IACK6 and IACK3–IACK1; AVEC (or AVECO) or IACK5; CS3 or
IACK7; AMUX or OE; A31–A28 or WE3–WE0.
Until the low byte of PEPAR is written, the WE3–WE0/A31–A28 pins are three-stated. The
PWW bit indicates whether the low byte of PEPAR was written. PEPAR may be read or writ-
ten at any time.
Bits 15, 11, and 3—Reserved
6-48
The address space bits for 040 type MPU are:
AS8—Not Relevant for 040 Cycles
AS7—Acknowledge Access(TT1-TT0=11)
AS6—Supervisor Code Access(TT1-TT0=00, TM2-TM0=110)
AS5—Supervisor Data Access(TT1-TT0=00, TM2-TM0=101)
AS4—MMU Table search Code Access (TT1-TT0=00, TM2-TM0=100)
AS3—MMU Table search Data Access(TT1-TT0=00, TM2-TM0=011)
AS2—User Code Access(TT1-TT0=00, TM2-TM0=010)
AS1—User Data Access(TT1-TT0=00, TM2-TM0=001)
AS0—Data Cache Push Access(TT1-TT0=00, TM2-TM0=000)
For each address space bit:
This bit indicates when the contents of the breakpoint address register and breakpoint
control register pair are valid. BKPT signal will not be asserted unless the valid bit is set.
0 = A breakpoint match can occur for this address space.
1 = Mask this address space from the breakpoint match logic. No breakpoint match will
0 = Contents not valid.
1 = Contents valid.
occur if this address space is used on a bus access.
