Signal Descriptions and Pin Assignments
2-3
CLKO
Clock Out signal selected from internal clock signals. Please refer to clock controller for
internal clock selection.
RESET_IN
Master Reset—External active low Schmitt trigger input signal. When this signal goes
active, all modules (except the reset module and the clock control module) are reset.
RESET_OUT
Reset Out—Internal active low output signal from the Watchdog Timer module and is
asserted from the following sources: Power-on reset, External reset (RESET_IN), and
Watchdog time-out.
POR
Power On Reset—Internal active high Schmitt trigger input signal. The POR signal is
normally generated by an external RC circuit designed to detect a power-up event.
JTAG
TRST
Test Reset Pin—External active low signal used to asynchronously initialize the JTAG
controller.
TDO
Serial Output for test instructions and data. Changes on the falling edge of TCK.
TDI
Serial Input for test instructions and data. Sampled on the rising edge of TCK.
TCK
Test Clock to synchronize test logic and control register access through the JTAG port.
TMS
Test Mode Select to sequence the JTAG test controller’s state machine. Sampled on the
rising edge of TCK.
System
BIG_ENDIAN
BIG_ENDIAN—This signal determines the memory endian configuration. BIG_ENDIAN is
a static pin to inner module. If the pin is driven logic-high the memory system is
configured into big endian. If it is driven logic-low the memory system is configured into
little endian. The pin is not supposed to be changed on the fly.
ETM
ETMTRACESYNC
ETM sync signal which is multiplexed with A24. ETMTRACESYNC is selected in ETM
mode.
ETMTRACECLK
ETM clock signal which is multiplexed with A23. ETMTRACECLK is selected in ETM
mode.
ETMPIPESTAT [2:0]
ETM status signals which are multiplex with A [22:20]. ETMPIPESTAT [2:0] are selected
in ETM mode.
ETMTRACEPKT [7:0]
ETM packet signals which are multiplex with ECB, LBA, BCLK, PA17, A [19:16].
ETMTRACEPKT [7:0] are selected in ETM mode.
CMOS Sensor Interface
CSI_D [7:0]
Sensor port data
CSI_MCLK
Sensor port master clock
CSI_VSYNC
Sensor port vertical sync
