8081 N/B Maintenance 5. Pin Descriptions of Major Components 5.1 Intel Banias Pentium M Processor Type Description A[31:3]# Signal Name I/O A20M# I A[31:3]# (Address) define a 2 32 -byte physical memory address space. In sub-phase 1 of the address phase, these pins transmit the address of a transaction. In sub-phase 2, these pins transmit transaction type information. These signals must connect the appropriate pins of both agents on the Intel Pentium M processor system bus.

8081 N/B Maintenance 5.1 Intel Banias Pentium M Processor Type Description INIT# Signal Name I LINT[1:0] I INIT# (Initialization), when asserted, resets integer registers inside the processor without affecting its internal caches or floating-point registers. The processor then begins execution at the power on Reset vector configured during power on configuration. The processor continues to handle snoop requests during INIT# assertion. INIT# is an asynchronous signal.
