Data Sheet
SDLC COMMUNICATIONS CONTROLLER
Errata
Errata data listed for a particular version of the device apply only to that version. If errata data
applies to more than one version it will be listed under each version affected. Errata data that
applies to all versions is listed under the heading “Version ALL”. InnovASIC devices are
manufactured as prototypes and production units. Prototype versions are denoted as ‘PXX‘ and
production versions are denoted as ‘XX’ with XX being the version number (i.e. 03).
Version ALL
:
ISSUE:
Cannot read internal ROM with EPROM verification method.
SOLUTION: Must use alternate method to read internal ROM. The IA8X44 does not contain
internal EPROM and therefore does not support the EPROM read feature.
ISSUE:
The IA8X44 has a different pullup value than the Intel version. The Intel version
can source more current than the IA8X44.
SOLUTION: Adjust external circuits if necessary.
Version P00
:
ISSUE:
Incorrect version of Intel 8044 code in internal ROM. Internal ROM contains
version 2.1 it should contain version 2.3.
SOLUTION: Version 2.3 ROM code must be run from external memory. Future versions of
device will contain version 2.3.
ISSUE:
The JMP @A+DPTR instruction incorrectly adds carry out of lower byte into higher
byte of calculated PC value (was using carry as if the @A was a signed value, should
be an absolute value).
SOLUTION: Avoid use of this instruction or modify code to account for error. Future versions of
device will execute this instruction correctly.
ISSUE:
When using edge sensitive interrupts the device may miss an interrupt. The problem
occurs when enabling the interrupts or when TCON is being written to.
SOLUTION: Change to level sensitive interrupts or use external registers for INT0/1.
ISSUE: Reads from unused internal locations return 00h. when they should return FFh except for
two locations which should return 00h.
SOLUTION: Avoid reading unused locations or mask the value from unused locations.
ISSUE:
Setting IE0 or IE1 in TCON does not force an interrupt when in level sensitive
mode.
SOLUTION: Use edge sensitive mode for these two interrupt sources.
