PCMCIA Interface
7-7
TS102 Registers
intended primarily for recovery from accidental erasure of the boot PROM
contents, but may also be used for such applications as field diagnostics, or
even OS upgrades.
It is also necessary to inhibit the generation of the SBus select to the
SLAVIO device when boot redirection is used, in order to prevent the
SLAVIO from from responding to accesses that are intended for the
PCMCIA interface, while still allowing access to all other SLAVIO
resources. When redirection is selected, the TS102 inhibits the SLAVIO
select if a decode of the SBus physical address indicates that the SLAVIO
would normally direct the cycle to the boot PROM.
7.3
TS102 Registers
There are two separate register blocks within the TS102. The first gives
access to PCMCIA card specific resources, and the second gives access to
the microcontroller interface. Table 7-4 summarizes the TS102’2 register
address map.
All registers are 16 bits wide and are can be read or written.
