MIL-STD-1553 Reference Manual
Chapter 5 – Buffer Functions
5 BUFFER FUNCTIONS
Chapter 5 defines the Buffer function calls of the API S/W Library. The Buffer functions
provide setup and status of the RT/BC global RAM message buffer memory area and the ASP
shared RAM dataset buffer area used for low speed and high speed message transfers. Table 5-I
defines the list and definition of Buffer functions. The function calls in this table are listed in a
functional order, however, the detailed descriptions of the Calibration function calls in the
following sections are in alphabetical order.
