No change.
In version 2.2.x, this signal is in the rrefclk
domain; in version 2.3.0, this signal is in the
rxsys_clk domain.
Removed from Signals table.
Transmitter Signals
In the 2.2.x versions of the MegaCore function, data is written to the Atlantic FIFO
buffers using the Atlantic clock ( aN_atxclk ). The logic, and reading from the Atlantic
FIFO buffer, is synchronous to trefclk / tx_coreclock (transmit clock). The SPI-4.2
transmit clock, tdclk , is generated from trefclk . Signals synchronous to trefclk are
infixed by _tc_ . The status processor is synchronous to tsclk . Signals synchronous to
tsclk are infixed by _ts_ . The external status signals in the shared buffer with
embedded addressing mode are synchronous to the Atlantic clock, a0_txclk .
In the 2.4.x and 2.3.x versions, the logic is synchronous to tdint_clk . The tdint_clk
clock is derived from trefclk . Signals synchronous to tdint_clk are infixed by _td_ .
Reading from the Atlantic FIFO buffer is always done using tdint_clk . In the single
clock domain mode, writing to the Atlantic FIFO buffer is synchronous to tdint_clk .
In the multiple clock domain mode, writing to the Atlantic FIFO buffer uses
aN_atxclk . For more information, refer to the “Clock Structure” section of the
In 2.4.x and 2.3.x versions of the MegaCore function, the status processor is
synchronous to tsclk ; however, the external status signals are in the txsys_clk
domain. The txsys_clk clock is an input to the MegaCore function, and may be set to
tsclk . Signals synchronous to tsclk are infixed by _ts_ , and signals synchronous to
txsys_clk are infixed by _ty_ .
