Receive data line of the SCI interface if a serial
interface is selected.
• Multiplexed Bus Mode:
Address/data bus
Address/data line AD7 if the parallel interface is
selected.
• Non-Multiplexed Bus Mode:
Data bus

interface is selected.
Read
Indicates a read access to the registers (Siemens/
Intel bus mode).
Data Strobe
The rising edge marks the end of a valid read or
write operation (Motorola bus mode).
Write
Indicates a write access to the registers (Siemens/
Intel bus mode).
Read/Write
A HIGH identifies a valid host access as a read
operation and a LOW identifies a valid host access
