PRODUCTION DATA
The serial communications port (SCP) is a full duplex, synchronous, character-oriented (byte) port that allows exchange of commands from the DLPC410 to the DLPA200s.
Five signal lines are associated with the SCP bus: SCPEN, SCPCK, SCPDI, SCPDO, and IRQ.
Table 8-4 lists the available controls and status pin names and their corresponding signal type, along with a brief functional description.
PIN NAME | DESCRIPTION | I/O |
---|---|---|
A_SCPEN | Active-low chip select for DLPA200 serial bus | O |
A_STROBE | DLPA200 control signal strobe | O |
A_MODE(1:0) | DLPA200 mode control | O |
A_SEL(1:0) | DLPA200 select control | O |
A_ADDR(3:0) | DLPA200 address control | O |
B_SCPEN | Active-low chip select for DLPA200 serial bus (2) | O |
B_STROBE | DLPA200 control signal strobe (2) | O |
B_MODE(1:0) | DLPA200 mode control | O |
B_SEL(1:0) | DLPA200 select control | O |
B_ADDR(3:0) | DLPA200 address control | O |
The DLPA200 provides a variety of output options to the DMD by selecting logic control inputs: MODE[1:0], SEL[1:0] and reset group address A[3:0] (Table 8-4). The MODE[1:0] input determines whether a single output, two outputs, four outputs, or all outputs, will be selected. Output levels (VBIAS, VOFFSET, or VRESET) are selected by SEL[1:0] pins. Selected outputs are tri-stated on the rising edge of the STROBE signal and latched to the selected voltage level after a break-before-make delay. Outputs will remain latched at the last micromirror clocking pulse waveform level until the next micromirror clocking pulse waveform cycle.
