Unbuffered data bus, bits 0 through 15


Unbuffered address bus, bits 1 through 23


16 MHz clock


External data transfer acknowledge. This signal is an input to the processor logic glue. Assertion delays external generation of the /DTACK signal.


E(enable) clock


Bus error signal generated whenever /AS remains low for more than about 250 us.


Input priority level lines 0 through 2.


Initiates a system reset.


A signal from the Power Manager indicated that associated circuits should tri-state their outputs and go inte idle state; /SYS.PWR is pulled high (deasserted) during sleep state.


Address strobe


Upper data strobe


Lower data strobe


Defines bus transfer as read or write signal


Data transfer acknowledge


Indicates that a wait state is inserted into the current memory cycle and that you can delay a CS.


Bus grant


Bus grant acknowledge


Bus request


Valid memory access


Valid peripheral address


Function code lines 0 through 2


Provides +5V when the system is running normally and 0V when the system is in sleep mode.


Provides +5V when the system is running normally and 3.7V when the system is in sleep mode.
