PD6708
3.1
Data Link Layer Controller
The data link layer controller performs processing of the IEBus protocol data link layer (frame composition and resolution,
communication error detection, etc.), execution of communication control commands set by the host controller, and generate
a return code that informs the host controller of the communication status.
3.2
Physical Layer Controller
The physical controller performs generation and resolution of bit timing and also converts the signals between the bus
lines through the driver/receiver.
3.3
IEBus Driver/Receiver
The driver/receiver performs conversion between the logic signals within the
μ
PD6708 and the IEBus signals. The IEBus
signals and their relationship to the logic statuses are shown in Table 3-1.
Table 3-1. Relationship between IEBus Signals and Logical Statuses
3.4
Host Interface
The host Interface is a block which controls the transmission and reception of data to and from the host controller. It
accepts communication control commands, passes on return codes, and forwards transmit data.
The forwarding of transmit data takes place through the FIFO buffers, 4 bytes of write data buffer (WDB) and 20 bytes
of read data buffer (RDB). It also absorbs the differences between IEBus transmission speed and the transmission speed
on the serial interface between the
μ
PD6708 and the host controller.
