ADDRESS DATA BUS: Input/Output
These lines are the multiplexed address and data bus.
These are the address bus at the T1 cycle and the data bus at the T2, T3, TW and T4 cycles.
At the T1 cycle, AD

ADDRESS/STATUS: Output
These are the four most significant addresses, at the T1 cycle. Accessing I/O port address,
these are low at T1 cycles. These lines are Status lines at T2, T3, TW and T4 cycles. S

BUS HIGH ENABLE/STATUS: Output
This line indicates Data Bus High Enable (BHE) at the T1 cycle. This line is status line at T2,
T3, TW and T4 cycles.
RD
READ: Output
This line indicates that CPU is in the memory or I/O read cycle.
This line is the read strobe signal when CPU read data from memory or I/O device. This line
is active low.
This line is high impedance during hold acknowledge.
READY
READY:Input
This line indicates to the CPU that the addressed memory or I/O device is ready to read or
write.
This line is active high. If the setup and hold time is out of specification, illegal operation will
occur.
INTR
INTERRUPT REQUEST: Input
This line is the level triggered interrupt request signal which is sampled during the last clock
cycle of instruction and string manipulation.
It can be internally masked by software.
This signal is active high and internally synchronized.
