USER’S MANUAL

an address that overlaps the address of the module control register block. Writing a

valid base address to TRAMBAR[15:3] clears RAMDS and enables the array.
TRAMBAR can be written only once after a master reset. This prevents runaway soft-

ware from accidentally re-mapping the array. Because the locking mechanism is acti-

vated by the first write after a master reset, the base address field should be written in

a single word operation. Writing only one-half of the register prevents the other half

from being written. Note that in test mode the locking mechanism for TRAMBAR can

be disabled by the RTBA bit in the TRAMTST register.

8.4 TPURAM Privilege Level

The RASP field in TRAMMCR specifies whether access to the TPURAM module can

be made from the supervisor privilege level only or from either the user or supervisor

privilege level. If supervisor-only access is specified, an access from the user privilege

level is ignored by the TPURAM control logic and can be decoded externally. Refer to

SECTION 4 SYSTEM INTEGRATION MODULE

SECTION 5 CENTRAL PRO-

CESSING UNIT

for more information concerning privilege levels.

8.5 Normal Operation

In normal operation, TPURAM is accessed via the IMB by a bus master and is pow-

ered by V

DD

. The array can be accessed by byte, word, or long word. A byte or aligned

word access takes one bus cycle (two system clock cycles). A long word access re-

quires two bus cycles. Refer to

SECTION 4 SYSTEM INTEGRATION MODULE

more information concerning access times.
During normal operation, the TPU does not access the array and has no effect on the

operation of the TPURAM module.

8.6 Standby Operation

Standby mode maintains the RAM array when the MCU main power supply is turned

off. Low-power mode allows the central processing unit to control MCU power con-

sumption.
Relative voltage levels of the V

DD

and V

STBY

pins determine whether the TPURAM

is in standby mode. TPURAM circuitry switches to the standby power source when

specified limits are exceeded. If specified standby supply voltage levels are main-

tained during the transition, there is no loss of memory when switching occurs. The

RAM array cannot be accessed while the TPURAM module is powered from V

STBY

.

If standby operation is not desired, connect the V

STBY

pin to the V

SS

pin.

I

exceeds specified maximum standby current during the time V

sition from normal operating level to the level specified for standby operation. This oc-

curs within the voltage range V

Refer to

APPENDIX A ELECTRICAL CHARACTERISTICS

for standby switching and

power consumption specifications.
To prevent standby supply voltage from going below the specified minimum, a filter ca-

pacitor must be attached between the V
