The transmit data signals (TXDATA[15:0])
contain the transmit Any-PHY packet interface
(APPI) data provided by the external controller.
Data must be presented in big endian order, i.e.
the byte in TXDATA[15:8] is transmitted by the
FREEDM-32A256 before the byte in
TXDATA[7:0].
address to identify the device and channel
associated with the data being transferred. This
prepended address must be qualified with the
TSX signal. The 8 least significant bits provide
the channel number (0 to 255) while the 3 most
significant bits select one of seven possible
FREEDM-32A256 devices sharing a single
external controller. (One address is reserved as
a null address.) The FREEDM-32A256 will not
respond to channel addresses outside the range
0 to 255, nor to device addresses other than the
base address stored in the TAPI256 Control
register.
The second and any subsequent words of each
data transfer contain packet data.
The TXDATA[15:0] signals are sampled on the
rising edge of TXCLK.
TXPRTY
Input
L4
The transmit parity signal (TXPRTY) reflects the
odd parity calculated over the TXDATA[15:0]
signals. TXPRTY is only valid when
TXDATA[15:0] are valid.
TXPRTY is sampled on the rising edge of
TXCLK.
