D0-D15
Unbuffered data bus, bits 0 through 15
A1-A23
Unbuffered address bus, bits 1 through 23
16M
16 MHz clock
/EXT.DTACK
External data transfer acknowledge. This signal is an input to the processor logic glue. Assertion delays external generation of the /DTACK signal.
E
E(enable) clock
/BERR
Bus error signal generated whenever /AS remains low for more than about 250 us.
/IPL0-/IPL2
Input priority level lines 0 through 2.
/SYS.RST
Initiates a system reset.
/SYS.PWR
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.
/AS
Address strobe
/UDS
Upper data strobe
/LDS
Lower data strobe
R/W
Defines bus transfer as read or write signal
/DTACK
Data transfer acknowledge
/DELAY.CS
Indicates that a wait state is inserted into the current memory cycle and that you can delay a CS.
/BG
Bus grant
/BGACK
Bus grant acknowledge
/BR
Bus request
/VMA
Valid memory access
/VPA
Valid peripheral address
FC0-FC2
Function code lines 0 through 2
+5/0V
Provides +5V when the system is running normally and 0V when the system is in sleep mode.
+5/3.7V
Provides +5V when the system is running normally and 3.7V when the system is in sleep mode.
