Host Interface (HI08)

Freescale Semiconductor

1.6 Host Interface (HI08)
The HI08 provides a fast, 8-bit, parallel data port that connects directly to the host bus. The HI08 supports a variety
of standard buses and connects directly to a number of industry-standard microcomputers, microprocessors, DSPs,
and DMA hardware.
1.6.1
Host Port Usage Considerations
Careful synchronization is required when the system reads multiple-bit registers that are written by another
asynchronous system. This is a common problem when two asynchronous systems are connected (as they are in the
Host port). The considerations for proper operation are discussed in Table 1-9.
1.6.2
Host Port Configuration
HI08 signal functions vary according to the programmed configuration of the interface as determined by the 16 bits
in the HI08 Port Control Register.
Table 1-9.
Host Port Usage Considerations
Action
Description
Asynchronous read of receive byte
registers
When reading the receive byte registers, Receive register High (RXH), Receive register Middle
(RXM), or Receive register Low (RXL), the host interface programmer should use interrupts or poll
the Receive register Data Full (RXDF) flag that indicates data is available. This assures that the data
in the receive byte registers is valid.
Asynchronous write to transmit byte
registers
The host interface programmer should not write to the transmit byte registers, Transmit register High
(TXH), Transmit register Middle (TXM), or Transmit register Low (TXL), unless the Transmit register
Data Empty (TXDE) bit is set indicating that the transmit byte registers are empty. This guarantees
that the transmit byte registers transfer valid data to the Host Receive (HRX) register.
Asynchronous write to host vector
The host interface programmer must change the Host Vector (HV) register only when the Host
Command bit (HC) is clear. This practice guarantees that the DSP interrupt control logic receives a
stable vector.

Input/Output
Input or Output
Ignored Input
Host Data—When the HI08 is programmed to interface with a non-multiplexed
host bus and the HI function is selected, these signals are lines 0–7 of the
bidirectional Data bus.
Host Address—When the HI08 is programmed to interface with a multiplexed
host bus and the HI function is selected, these signals are lines 0–7 of the
bidirectional multiplexed Address/Data bus.
Port B 0–7—When the HI08 is configured as GPIO through the HI08 Port
Control Register, these signals are individually programmed as inputs or outputs
through the HI08 Data Direction Register.
