FREEDM 32A1024L ASSP Telecom Standard Product Data Sheet
Function
TPA_xx are 0 when an unprovisioned channel is polled.
Any-PHY Level 2 Mode
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 32A1024L before
the byte in TXDATA[7:0].
The first word of each data transfer contains an address to identify
the device and Any-PHY channel associated with the data being
transferred. This prepended address must be qualified with the
TSX signal. The FREEDM 32A1024L compares the first two bytes
to the base and range registers to determine if the Any-PHY
channel resides within the FREEDM 32A1024L.The FREEDM
32A1024L will not respond to Any-PHY channel addresses outside
the high and low address registers stored in the TAPI-12 base and
range address registers.
Bit 10 of the prepended address indicates the priority level of the
data. Bit 10 = 0 indicates low priority and Bit 10 = 1 indicates high
priority.
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.
Any-PHY Level 3 Mode:
The transmit data signals (TXDATA[7:0]) contain the transmit Any-
PHY packet interface (APPI) data provided by the external
controller.
The first two bytes of each data transfer contains an address to
identify the device and Any-PHY channel associated with the data
being transferred. The first byte of this prepended address must be
qualified with the TSX signal. The FREEDM 32A1024L compares
the first two bytes to the TAPI-12 base and range registers to
determine if the Any-PHY channel resides within the FREEDM
32A1024L.The FREEDM 32A1024L will not respond to Any-PHY
channel addresses outside the base and range registers.
Bit 10 of the prepended address (bit 2 of the first byte of the
transfer) indicates the priority level of the data. Bit 10 = 0 indicates
low priority and Bit 10 = 1 indicates high priority.
The third and any subsequent bytes of each data transfer contain
packet data.
The TXDATA[7:0] signals are sampled on the rising edge of
TXCLK.
TXDATA[15:8] are not used by FREEDM 32A1024L when
operating in Any-PHY Level 3 mode and should be tied low.
Any-PHY Level 2 Mode:
The transmit parity signal (TXPRTY) reflects the odd parity
calculated over the TXDATA[15:0] signals (regardless of TMOD
state). TXPRTY is only valid when TXDATA[15:0] are valid.
Any-PHY Level 3 Mode:
The transmit parity signal (TXPRTY) reflects the odd parity
calculated over the TXDATA[7:0] signals. TXPRTY is only valid
when TXDATA[7:0] are valid.
Regardless of mode of operation TXPRTY is sampled on the rising
