FREEDM 84A1024L ASSP Telecom Standard Product Data Sheet
Function
RERR is tristated when the FREEDM 84A1024L device is not
selected via the RENB signal.
Any-PHY Level 3 Mode:
RERR is driven low when the FREEDM 84A1024L device is
not selected via the RENB signal.
The receive data valid (RVAL) is asserted when packet data is
being output on RXDATA. It is de-asserted whenever the
FREEDM 84A1024L device is selected, but not outputting
packet data on RXDATA[15:0]. (E.g., when RSX is high and
address prepend is being output on RXDATA, RVAL is de-
asserted.)
RVAL is updated on the rising edge of RXCLK.
Any-PHY Level 2 Mode:
RVAL is tristated when the FREEDM 84A1024L device is not
selected via the RENB signal.
Any-PHY Level 3 Mode:
RVAL is driven low when the FREEDM 84A1024L device is
not selected via the RENB signal.
Function
Re-Sequencing SDRAM Chip Select Bar. RSCSB,
RSRASB, RSCASB, and RSWEB define the command
being sent to the SDRAM.
RSCSB is updated on the rising edge of SYSCLK.
Re-Sequencing SDRAM Row Address Strobe Bar.
RSCSB, RSRASB, RSCASB, and RSWEB define the
command being sent to the SDRAM.
RSRASB is updated on the rising edge of SYSCLK.
Re-Sequencing SDRAM Column Address Strobe Bar.
RSCSB, RSRASB, RSCASB, and RSWEB define the
command being sent to the SDRAM.
RSCASB is updated on the rising edge of SYSCLK.
Re-Sequencing SDRAM Write Enable Bar. RSCSB,
RSRASB, RSCASB, and RSWEB define the command
being sent to the SDRAM.
RSWEB is updated on the rising edge of SYSCLK.
Re-Sequencing SDRAM Address. The Re-Sequencing
SDRAM address outputs identify the row address
(RSADD[12:0]) and column address (RSADD[8:0]) for the
locations accessed.
RSADD[12:0] is updated on the rising edge of SYSCLK.
