HS=ENABLED, INV=INPUT_NOT_INVERTED_, FUNC=P0_28, HIDRIVE=LOWDRIVE
I/O configuration register for pin P0[28]
| FUNC | Selects pin function for pin P0[28] 0 (P0_28): General purpose digital input/output pin. 1 (I2C0_SCL): I2C0 clock input/output (this pin uses a specialized I2C pad. 2 (USB_SCL1): I2C serial clock for communication with an external USB transceiver. |
| RESERVED | Reserved. |
| INV | Invert input 0 (INPUT_NOT_INVERTED_): Input not inverted (HIGH on pin reads as 1, LOW on pin reads as 0). 1 (INPUT_INVERTED_HIGH): Input inverted (HIGH on pin reads as 0, LOW on pin reads as 1). |
| RESERVED | Reserved. |
| HS | Configures I2C features for standard mode, fast mode, and Fast Mode Plus operation. 0 (ENABLED): I2C 50ns glitch filter and slew rate control enabled. 1 (DISABLED): I2C 50ns glitch filter and slew rate control disabled. |
| HIDRIVE | Controls sink current capability of the pin, only for P5[2] and P5[3]. 0 (LOWDRIVE): Output drive sink is 4 mA. This is sufficient for standard and fast mode I2C. 1 (HIGHDRIVE): Output drive sink is 20 mA. This is needed for Fast Mode Plus I2C. Refer to the appropriate specific device data sheet for details. |
