Pin
Type
Function
ADDR25–2
DATA31–0
O/T
I/O/T External data bus. (Pin has a logic-level hold circuit that prevents the input from floating
internally.)
O/T
Asynchronous memory byte enables SDRAM data masks.
O/T
Chip selects for asynchronous memories.
I
Acknowledge signal for asynchronous memories.
O/T
Memory output enable for asynchronous memories.
O
Read enable for asynchronous memories.
O
Write enable for asynchronous memories.
O
SDRAM clock output pin. Same frequency and timing as SCLK0. Provided to reduce
capacitance loading on SCLK0. Connect to SDRAM’s CK pin.
O
SDRAM clock output pin 0. Switches at system clock frequency. Connect to the
SDRAM’s CK pin.
O/T
SDRAM clock enable pin. Connect to SDRAM’s CKE pin.
O/T
SDRAM A10 pin. SDRAM interface uses this pin to retain control of the SDRAM device
during host bus requests. Connect to SDRAM’s A10 pin.
O/T
SDRAM row address strobe pin. Connect to SDRAM’s RAS pin.
O/T
SDRAM column address select pin. Connect to SDRAM’s CAS pin.
O/T
SDRAM write enable pin. Connect to SDRAM’s WE or W buffer pin.
O/T
Memory select pin of external memory bank configured for SDRAM. Connect to
SDRAM’s chip select pin.
I/O/T Timer 0 pin. Functions as an output pin in PWMOUT mode and as an input pin in
WIDTH_CNT and EXT_CLK modes.
I/O/T Timer 1 pin. Functions as an output pin in PWMOUT mode and as an input pin in
WIDTH_CNT and EXT_CLK modes.
I/O/T Timer 2 pin. Functions as an output pin in PWMOUT mode and as an input pin in
WIDTH_CNT and EXT_CLK modes.
I/O/T Programmable flag pin. SPI output select pin.
I/O/T Programmable flag pin. SPI output select pin.
I/O/T Programmable flag pin. SPI output select pin.
I/O/T Programmable flag pin. SPI output select pin.
I/O/T Programmable flag pin. SPI output select pin.
I/O/T Programmable flag pin. SPI output select pin (used during SPI boot).
I/O
Programmable flag pin. SPI output select pin. Sampled during reset to determine core
clock to system clock ratio.
I/O
Programmable flag pin. SPI output select pin. Sampled during reset to determine core
clock to system clock ratio.
I/O
Programmable flag pin. SPI output select pin. Sensed for configuration state during
hardware reset, used to configure the PLL. DF = 1 is for high frequency clock and divides
the input clock by 2. DF = 0 passes input clock directly to PLL phase detector.
PF6/
SPI0SEL3
/MSEL6 I/O
Programmable flag pin. SPI output select pin. Sensed for configuration state during
hardware reset, used to configure the PLL. Selects CK to CLKIN ratio.
PF5/
SPI1SEL2
/MSEL5 I/O
Programmable flag pin. SPI output select pin. Sensed for configuration state during
hardware reset, used to configure the PLL. Selects CK to CLKIN ratio.
