FUNC=P5_3, HIDRIVE=LOWDRIVE, HS=ENABLED, INV=INPUT_NOT_INVERTED_
I/O configuration register for pin P5[3]
| FUNC | Selects pin function for pin P5[3] 0 (P5_3): General purpose digital input/output pin. 4 (U4_RXD): Receiver input for USART4. 5 (I2C0_SCL): I2C0 clock input/output (this pin uses a specialized I2C pad that supports I2C Fast Mode Plus. |
| 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. |
