INTERFACING WITH HOST CONTROLLER
This chapter will explain the interfacing that occurs between the
μ
PD6708 and the host controller.
4.1
Accessible Buffers and Registers from Host Controller
The host controller, which controls the
μ
PD6708, can access the write data (WDB), the read data buffer (RDB), the
command register (CMR), and the status register (STR) within the
μ
PD6708.
4.1.1
Write data buffer (WDB)
WDB is a 4-byte FIFO buffer in which the host controller transmit data and the parameters of the communication control
commands are written.
4.1.2
Read data buffer (RDB)
RDB is a 20-byte FIFO buffer which stores the receive data acknowledged by the data link layer controller in the
μ
PD6708.
The host controller reads the
μ
PD6708 receive data from RDB.
4.1.3
Command register (CMR)
CMR is an 8-bit register used to write control commands for the
μ
PD6708.
As shown in Table 4-1, the host controller sets the reset mode and the host interface mode in higher 4 bits and sets the
communication control command code in lower 4 bits.
