Preliminary Data Sheet
Pin Listing

No.
187 CarrBp
Pin label
Type
I/O
pd
Enable / disable carrier based backpressure for half -duplex mode.
'1' – Carrier based backpressure
‘0' – Collision based backpressure.
CarrBp is latched on reset
I/O
pd
Setting this pin to ‘1’ will disable backpressure procedure for all half
duplex ports. DisBkPr is latched upon reset.
I/O
pd
Setting this bit to ‘1’ will force flow control execution for 10/100Mbps,
no matter the auto negotiation result. FrcFdFc is latched upon reset.
G
Digital ground for I/O
I/O
pd
Setting this bit to '1' will disable flow-control for full-duplex mode
(transmission of pause frames).
DisFdFc is latched upon reset.
I/O
pd
Enable / disable backoff during backpressure.
'1' – No backoff executed. Another collision will be forced again after one
minimum IFG time following previous collision if carrier sense is
observed.
'0' – The MAC randomly chooses between 0 and 1 slot times of backoff.
DisBkBp is latched during the reset operation.
