ADSP-BF606/ADSP-BF607/ADSP-BF608/ADSP-BF609
ETH_CRS Input Carrier Sense/RMII Receive Data Valid Multiplexed on alternate clock cycles.
CRS: Asserted by the PHY when either the transmit or receive medium is not idle. De-asserted when both
are idle.
RXDV: Asserted by the PHY when the data on RXDn is valid.
ETH_MDC Output Management Channel Clock Clocks the MDC input of the PHY.
ETH_MDIO I/O Management Channel Serial Data Bidirectional data bus for PHY control.
ETH_PTPAUXIN Input PTP Auxiliary Trigger Input Assert this signal to take an auxiliary snapshot of the time and store it in
the auxiliary time stamp FIFO.
ETH_PTPCLKIN Input PTP Clock Input Optional external PTP clock input.
ETH_PTPPPS Output PTP Pulse-Per-Second Output When the Advanced Time Stamp feature is enabled, this signal is
asserted based on the PPS mode selected. Otherwise, PTPPPS is asserted every time the seconds counter
is incremented.
ETH_REFCLK Input Reference Clock Externally supplied Ethernet clock.
ETH_RXDn Input Receive Data n Receive data bus.
ETH_TXDn Output Transmit Data n Transmit data bus.
ETH_TXEN I/O Transmit Enable When asserted indicates that the data on TXDn is valid.
JTG_EMU
Output Emulation Output JTAG emulation flag.
JTG_TCK Input Clock JTAG test access port clock.
JTG_TDI Input Serial Data In JTAG test access port data input.
JTG_TDO Output Serial Data Out JTAG test access port data output.
JTG_TMS Input Mode Select JTAG test access port mode select.
JTG_TRST
Input Reset JTAG test access port reset.
LP_ACK I/O Acknowledge Provides handshaking. When the link port is configured as a receiver, ACK is an output.
When the link port is configured as a transmitter, ACK is an input.
LP_CLK I/O Clock When the link port is configured as a receiver, CLK is an input. When the link port is configured as
a transmitter, CLK is an output.
LP_Dn I/O Data n Data bus. Input when receiving, output when transmitting.
PPI_CLK I/O Clock Input in external clock mode, output in internal clock mode.
PPI_Dnn I/O Data n Bidirectional data bus.
PPI_FS1 I/O Frame Sync 1 (HSYNC) Behavior depends on PPI mode. See the PPI chapter in the processor hardware
reference for more details.
PPI_FS2 I/O Frame Sync 2 (VSYNC) Behavior depends on PPI mode. See the PPI chapter in the processor hardware
reference for more details.
PPI_FS3 I/O Frame Sync 3 (FIELD) Behavior depends on PPI mode. See the PPI chapter in the processor hardware
reference for more details.
PWM_AH Output Channel A High Side High side drive signal.
PWM_AL Output Channel A Low Side Low side drive signal.
PWM_BH Output Channel B High Side High side drive signal.
PWM_BL Output Channel B Low Side Low side drive signal.
PWM_CH Output Channel C High Side High side drive signal.
PWM_CL Output Channel C Low Side Low side drive signal.
PWM_DH Output Channel D High Side High side drive signal.
PWM_DL Output Channel D Low Side Low side drive signal.
PWM_SYNC Input PWM External Sync This input is for an externally generated sync signal. If the sync signal is internally
generated no connection is necessary.
PWM_TRIPn
Input Shutdown Input n When asserted the selected PWM channel outputs are shut down immediately.
Px_nn I/O Position n General purpose input/output. See the GP Ports chapter in the processor hardware reference
for programming information.
