TABLE 8.5 EXTERNAL INTERRUPT REQUEST REGISTER
8.1.6 AIRs (Architecture Invisible Registers)
There are eight AIRs in the W90100. AIR[0] controls the internal cache configuration, burst mode,
and default endian. AIR[0] is documented in this data sheet. AIR[1] and AIR[2] are reserved for chip testing by
Winbond, and their functions will not be disclosed to users. Attempting to access these two registers may
cause programs to be executed with unpredictable results. Memory configuration registers are used for
programming the configuration of W90100 memory space. AIR[7] is the PCO register, this AIR can only be
accessed through the JTAG ICE interface.
