CS8920A
Memory Base Address (Read/Write)
Address 0348h
Memory base address, high byte.
Address: PacketPage base + 0348h
Address 0349h
Memory base address, low byte.
After reset, if no EEPROM is found by the CS8920A, the register has the following initial state. If an EEPROM is
found, the register’s initial value may be set by the EEPROM. The memory mode is disabled when the memory
base register is 0000 0000.
0000 0000 0000 0000
I/O Base Address (Read/Write)
Address 0360h
Most significant byte of I/O Base Address
Address: PacketPage base + 0360h
Address 0361h
Least significant byte of I/O Base Address
The I/O Base Address Register describes the base address for the sixteen contiguous locations in the host
system’s I/O space, which are used to access the PacketPage registers. See Section 4.12. The CS8920A IO
mode is disabled if IO base register is 0000
After reset, if no EEPROM is found by the CS8920A, the register has the following initial state. If an EEPROM is
found, the register’s initial value may be set by the EEPROM. See Section 3.3.
