Z89135/136 (ROMless)
Low-Cost DTAD Controller
DSP-Z8 MAILBOX
To receive information from the DSP, the Z8 uses eight in-
coming registers which are mapped in the Z8 extended
Register File (Bank B, 08 to 0F). The DSP treats these as
four 16-bit registers that correspond to the eight incoming
Z8 registers (Figure 30).
Both the outgoing registers and the incoming registers
share the same DSP address (EXT3-EXT0).

The Z8 can supply the DSP with data through eight outgo-
ing registers mapped into both the Z8 Expanded Register
File (Bank B, Registers 00 to 07) and the external register
interface of the DSP. These registers are Read/Write and
can be used as general-purpose registers of the Z8. The
DSP can only read information from these registers. Since
the DSP uses a 16-bit data format and the Z8 an 8-bit data
format, eight outgoing registers of the Z8 correspond to
four DSP registers. The DSP can only read information
from the outgoing registers.
Note: The Z8 can read and write to ERF Bank B R00-R07,
Registers 08-0F are Read Only from the Z8.
