PRODUCTION DATA
PIN | I/O (1) | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
IIC0_SCL | AL25 | B18 | I2C Port 0 (Primary-Secondary), Typically Secondary for Host Command and Control to Controller, SCL (bidirectional, open-drain): An external pullup is required. The minimum acceptable value for this pullup is 470Ω. |
IIC0_SDA | AK24 | B18 | |
SSP0_DO | AP24 | O17 | SSP/SPI Port 0 Data Out (Primary): Transmit data pin. |
SSP0_DI | AN23 | I3 | SSP/SPI Port 0 Data In (Primary): Receive data pin. |
SSP0_CLK | AN25 | O17 | SSP/SPI Port 0 Clock (Primary): Clock pin. |
SSP0_CSZ_0 | AM22 | O17 | SPI Port 0 chip select 0 (Primary): Chip select (Active Low). An external pullup resistor (≤ 10kΩ) is suggested to avoid a floating chip select input to the external device. |
USB_DAT_P | AU1 | B7 | USB OTG Data Lane |
USB_DAT_N | AW1 | B7 | |
USB_VBUS | AP4 | B7 | USB OTG 5V Power Supply Detection |
USB_ID | AT2 | I7 | USB OTG Mini Receptacle Identification. |
USB_TXRTUNE | AR3 | PWR | RTTRIM USB OTG Reference Resistor: An external reference resistor, for calibrating the on-chip resistors, must be connected with a value of 499Ω. |
HOST_IRQ | AK22 | O17 | Host interrupt (output): HOST_IRQ indicates when the DLPC auto-initialization is in progress and most importantly when it completes. The HOST_IRQ also toggles during command handling to indicate when the execution is in progress. This pin is tristated during reset. An external pullup must be included on this signal. |
