Type Description
Non-Flash Booting Interface
204
I Management Data Clock in NFBI Mode.
This pin provides a clock synchronous to MDIO. The clock
rate can be from DC to 25MHz.
205
I/O Management Data I/O on NFBI Mode.
NFBI access data Input/Output and it is synchronous with
the rising edge of MDC clock input.
The Timing specification and frame format follow IEEE
802.3 SMI (MDC/MDIO) interface specifications.
206
O Interrupt to Host on NFBI Mode.
Used by NFBI to interrupt the external host CPU.
This pin is Level trigger. Level polarity can be programmed
by CMD register.
202
I Chip Reboot in NFBI Mode.
When the external host needs to reboot the RTL8198 CPU,
this pin must be asserted to LOW. This pin should be always
pulled-up in Non-flash booting mode.
203
I GMII Test Mode.
0: GMII test mode
1: GMII normal mode
This pin should be always pulled-up in Non-flash booting
mode.
