STRB — Address Strobe/Data Strobe
0 = Address strobe
1 = Data strobe
This bit controls the timing for assertion of a chip select in asynchronous mode. Selecting address
strobe causes chip select to be asserted synchronized with address strobe. Selecting data strobe caus-
es chip select to be asserted synchronized with data strobe.
DSACK — Data Strobe Acknowledge
This field specifies the source of DSACK in asynchronous mode. It also allows the user to adjust bus
timing with internal DSACK generation by controlling the number of wait states that are inserted to op-
timize bus speed in a particular application. The following table shows the DSACK field encoding. A no-
wait encoding (%0000) corresponds to a three clock-cycle bus. The fast termination encoding (%1110)
corresponds to a two clock-cycle bus — microcontroller modules typically respond at this rate, but fast
termination can also be used to access fast external memory.
SPACE — Address Space
This option field is used to select an address space to be used by the chip select logic. The CPU16 nor-
mally operates in supervisor space — all space types can be used. Interrupt acknowledge cycles take
place in CPU space.
IPL — Interrupt Priority Level
When the space field is set for CPU space (%00), chip select logic can be used for interrupt acknowl-
edge. During an interrupt acknowledge cycle, the priority level on address lines ADDR[3:1] is compared
to the value in the IPL field. If the values are the same, then a chip select can be asserted, provided
other option register conditions are met. When the Space field has any value except %00, the IPL field
determines whether an access takes place in program or data space. The following table shows IPL field
encoding.
