ADDRESS MAPS
Table 3.1: IP220 I/O Space Address Memory Ma
Notes (Table 3.1):
1.
The IP will not respond to addresses that are "Not Used".
2. Channels 8-15 are present in the IP220-16 Model, only.
The following sections give details on the function of each
location in the I/O space noted above.
IP Identification PROM - (Read Only, 32 odd-byte addresses)
Each IP module contains an identification (ID) PROM that
resides in the ID space per the IP module specification. This area of
memory contains 32 bytes of information at most. Both fixed and
variable information may be present within the ID PROM. Fixed
information includes the "IPAC" identifier, model number, and
manufacturer's identification codes. Variable information includes
unique information required for the module. The IP220 ID PROM
bytes are addressed using only the odd addresses in a 64-byte
block. The IP220 ID PROM contents are shown in Table 3.2. Note
that the base-address for the IP module ID space (see your carrier
board instructions) must be added to the addresses shown to
properly access the ID PROM. Execution of an ID PROM Read
requires 0 wait states.

DAC Channel Registers- (Write, Base + OOH to Base + lEH)
The
IP220 contains sixteen (16) DAC Channel Registers in the
I/O space. Writing to the address of the specific register enables
the 12-bit input buffer, of the 12-bit input double buffer, to latch the
data existing on the data bus. The 12-bit DAC registers are written
(will not respond to reads) with 16-bit words (D16) with the four least
significant bits (D3 to DO) being non-functional during a digital to
analog conversion cycle. Execution of a DAC Channel Write
command requires 0 wait states.
