5.6 Peripheral Interface

PIN(1)I/OTYPE(2)DESCRIPTION
NAMENO.
CMP_OUTA12I6Successive approximation ADC (analog-to-digital converter) comparator output (DLPC34xx Input). To implement, use a successive approximation ADC with a thermistor feeding one input of the external comparator and the DLPC34xx controller GPIO_10 (RC_CHARGE) pin driving the other side of the comparator. It is recommended to use the DLPAxxxx to achieve this function. CMP_OUT must be pulled-down to ground if this function is not used. (hysteresis buffer)
CMP_PWMA15O1TI internal use. Leave this pin unconnected.
HOST_IRQ(3)N8O9Host interrupt (output)
HOST_IRQ indicates when the DLPC34xx auto-initialization is in progress and most importantly when it completes.
This pin is tri-stated during reset. An external pullup must be included on this signal.
IIC0_SCL(4)N10I/O7I2C secondary (port 0) SCL (bidirectional, open-drain signal with input hysteresis): This pin requires an external pullup resistor. The secondary I2C I/Os are 3.6-V tolerant (high-voltage-input tolerant) and are powered by VCC_INTF (which can be 1.8, 2.5, or 3.3 V). External I2C pullups must be connected to a host supply with an equal or higher supply voltage, up to a maximum of 3.6 V (a lower pullup supply voltage does not typically satisfy the VIH specification of the secondary I2C input buffers).
IIC1_SCLR11I/O8TI internal use. TI recommends an external pullup resistor.
IIC0_SDA(4)N9I/O7I2C secondary (port 0) SDA. (bidirectional, open-drain signal with input hysteresis): This pin requires an external pullup resistor. The secondary I2C port is the control port of controller. The secondary I2C I/O pins are 3.6-V tolerant (high-volt-input tolerant) and are powered by VCC_INTF (which can be 1.8, 2.5, or 3.3 V). External I2C pullups must be connected to a host supply with an equal or higher supply voltage, up to a maximum of 3.6 V (a lower pullup supply voltage does not typically satisfy the VIH specification of the secondary I2C input buffers).
IIC1_SDAR10I/O8TI internal use. TI recommends an external pullup resistor.

LED_SEL_1B14O1The controller drives these signals low when RESETZ is asserted and the corresponding I/O power is supplied. The controller continues to drive these signals low throughout the auto-initialization process. A weak, external pulldown resistor is recommended to ensure that the LEDs are disabled when I/O power is not applied.
SPI0_CLKA13O13SPI (Serial Peripheral Interface) port 0, clock. This pin is typically connected to the flash memory clock.
SPI0_CSZ0A14O13SPI port 0, chip select 0 (active low output). This pin is typically connected to the flash memory chip select.
TI recommends an external pullup resistor to avoid floating inputs to the external SPI device during controller reset assertion.
SPI0_CSZ1C12O13SPI port 0, chip select 1 (active low output). This pin typically remains unused.
TI recommends an external pullup resistor to avoid floating inputs to the external SPI device during controller reset assertion.
SPI0_DINB12I12Synchronous serial port 0, receive data in. This pin is typically connected to the flash memory data out.
SPI0_DOUTB13O13Synchronous serial port 0, transmit data out. This pin is typically connected to the flash memory data in.
(1) External pullup resistor must be 8 kΩ or less.
(2) See Table 5-2 for type definitions.
(3) For more information about usage, see Section 7.3.2.
(4) When VCC_INTF is powered and VDD is not powered, the controller may drive the IIC0_xxx pins low which prevents communication on this I2C bus. Do not power up the VCC_INTF pin before powering up the VDD pin for any system that has additional secondary devices on this bus.
