7.2 Configuration registers
7.2.1
Function 0 configuration registers
UCB1500 supports the PCI configuration cycle to control the UCB1500 access. It
sets up the PCI configuration bits and the UCB1500 IO port address. The following
table shows the supported PCI registers and their default values. Some of the
registers are programmable through the EEPROM interface (See EEPROM section
for details).
Remark:
All registers are read/write, unless specified otherwise. Shaded registers
are read-only. A register with (S) means it is powered by V
AUX
and is sticky. Unless
sticky or otherwise stated, all read/write registers defaults to zero at PCI reset. All
reserved or unimplemented registers are hardwired to 0.
