Implementation consists of a set of functions burnt in to the PROM
|
|
on the card and providing the following set of functions (see below
|
|
for PROM revision history on functions supported by particular PROM
|
|
revision):
|
|
.Pp
|

|
|
.It
|

|
|
.It

|
|
.El
|
|
.Pp
|
|
There are two modes for accessing the PROM:
|
|
.Dq byte
|
|
and
|
|
.Dq word
|
|
mode.
|
|
In
|
|
.Dq byte
|
|
mode each 4-byte word contains only the low-ordered big-endian
|
|
byte of data; i.e., to compose one word of data 4 words should be read
|
|
and low-ordered bytes of those should be shifted correspondingly.
|
|
In
|
|
.Dq word
|
|
mode each word contains all 4 bytes of valid data.
