Ball Function Description
Serial bus configuration pins to select mode of access to
KSZ8893MBL internal registers.
[PS1, PS0] = [0, 0] — I
(If EEPROM is not detected, the KSZ8893MBL will be
configured with the default values of its internal registers and
the values of its strap-in pins.)
[PS1, PS0] = [0, 1] — I
The external I
The KSZ8893MBL device addresses are:
1011_1111
1011_1110
[PS1, PS0] = [1, 0] — SPI slave mode
[PS1, PS0] = [1, 1] – SMI-mode
In this mode, the KSZ8893MBL provides access to all its
internal 8-bit registers through its MDC and MDIO pins.
Note:
When (PS1, PS0) ≠ (1,1), the KSZ8893MBL provides access
to its 16-bit MIIM registers through its MDC and MDIO pins.
