Receive Buffer Write Page Pointer Register: RWP (Reg17h/16h), R/W, default=x000h
Bit
16.7-0,
17.3-0
Symbol
RWP[11:0]
Description
Receive Buffer Write Page Pointer: Current receive write page pointer. The MSB
is the Reg17h.3 bit. The LSB is the Reg16h.0 bit. This register is controlled by
GMAC only. An internal Byte Counter (RWPBC) is associated with this page
register.
Receive Buffer Read Page Pointer Register: RRP ( Reg19h/18h), R/W, default=0000h
Bit
18.7-0,
19.3-0
Symbol
RRP[11:0]
Description
Receive buffer Read Page Pointer: Current receive read page pointer. RRP[11:0]
is mapped to MA[19:8]. The MSB is the Reg19h.3 bit. The LSB is the Reg18h.0
bit. This register is normally controlled by the device driver. An internal Byte
Counter (RRPBC) is associated with this page register.
RX High Boundary Page Pointer Register: RHBP Reg.1Bh/1Ah, R/W, default=x000h
Bit
1A.7-0.
1B.3-0
Symbol
RHBP[11:0]
Description
Receive High Boundary Page Pointer : The RX packet buffer is defined as
between RHBP [11:0] and BP[11:0]. The MSB is the Reg1Bh.3 bit. The LSB is
Reg1Ah.0 bit.
Receive Interrupt Timer: RXINTT (Reg15h/14h), R/W, default=0000h
Bit
14.7-0,
15.7-0
Symbol
RXINTT[7:0],
RXINTT[15:8]
Description
Receive Interrupt Timer: Default is 0000h, meaning no time-out is used on the RI
or the REI interrupt assertion. Reg15h.7 is the RXINTT.15 bit. Reg14h.0 is
the RXINTT.0 bit. Any non-zero value enables the time out function if RXINTC[1:0]
(Reg01h.[7:6] ) > 0. The time unit of this counter is 40ns per count. The possible
timeout period ranges from 40ns to 2622 us. When the RXINTT times out, if the
received packet count has not reached the RXINTC [1:0], an interrupt will be
generated (which is caused by the RXINTT timeout alone). Depending on the
Reg50.4 bit, RXINTT will start counting after the end of the last receive
packet of either the host DMA or the RX local DMA. See waveform diagram about
"RXINTT start time definifion."
