Signals and Connections
Table 2. i.MX1 Signal Descriptions (Continued)
Signal Name
Function/Notes
DMA
DMA_REQ
BIG_ENDIAN
DMA Request—external DMA request signal. Multiplexed with SPI1_SPI_RDY.
Big Endian—Input signal that determines the configuration of the external chip-select space. If it is
driven logic-high at reset, the external chip-select space will be configured to big endian. If it is driven
logic-low at reset, the external chip-select space will be configured to little endian. This input must not
change state after power-on reset negates or during chip operation.
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 multiplexed with A [22:20]. ETMPIPESTAT [2:0] are selected in ETM
mode.
ETMTRACEPKT [7:0] ETM packet signals which are multiplexed with ECB, LBA, BCLK (burst clock), PA17, A [19:16].
ETMTRACEPKT [7:0] are selected in ETM mode.

LCD Controller
LD [15:0]
FLM/VSYNC
LP/HSYNC
LSCLK
ACD/OE
CONTRAST
SPL_SPR
PS
CLS
REV
LCD Data Bus—All LCD signals are driven low after reset and when LCD is off.
Frame Sync or Vsync—This signal also serves as the clock signal output for the gate
driver (dedicated signal SPS for Sharp panel HR-TFT).
Line pulse or H sync
Shift clock
Alternate crystal direction/output enable.
This signal is used to control the LCD bias voltage as contrast control.
Program horizontal scan direction (Sharp panel dedicated signal).
Control signal output for source driver (Sharp panel dedicated signal).
Start signal output for gate driver. This signal is an inverted version of PS (Sharp panel dedicated
signal).
Signal for common electrode driving signal preparation (Sharp panel dedicated signal).
