EPD=DISABLE_PULL_DOWN, ZIF=ENABLE_INPUT_FILTER, EZI=DISABLE_INPUT_BUFFER, EHS=FAST_LOW_NOISE_WITH, EPUN=ENABLE_PULL_UP, MODE=FUNCTION_0_DEFAULT
Pin configuration register for pins CLK
| MODE | Select pin function. 0 (FUNCTION_0_DEFAULT): Function 0 (default) 1 (FUNCTION_1): Function 1 2 (FUNCTION_2): Function 2 3 (FUNCTION_3): Function 3 4 (FUNCTION_4): Function 4 5 (FUNCTION_5): Function 5 6 (FUNCTION_6): Function 6 7 (FUNCTION_7): Function 7 |
| EPD | Enable pull-down resistor at pad. 0 (DISABLE_PULL_DOWN): Disable pull-down. 1 (ENABLE_PULL_DOWN): Enable pull-down. Enable both pull-down resistor and pull-up resistor for repeater mode. |
| EPUN | Disable pull-up resistor at pad. By default, the pull-up resistor is enabled at reset. 0 (ENABLE_PULL_UP): Enable pull-up. Enable both pull-down resistor and pull-up resistor for repeater mode. 1 (DISABLE_PULL_UP): Disable pull-up. |
| EHS | Slew rate 0 (FAST_LOW_NOISE_WITH): Fast (low noise with fast speed) 1 (HIGH_SPEED_MEDIUM_N): High-speed (medium noise with high speed) |
| EZI | Input buffer enable. The input buffer is disabled by default at reset and must be enabled for receiving. 0 (DISABLE_INPUT_BUFFER): Disable input buffer 1 (ENABLE_INPUT_BUFFER): Enable input buffer |
| ZIF | Input glitch filter. Disable the input glitch filter for clocking signals higher than 30 MHz. 0 (ENABLE_INPUT_FILTER): Enable input filter 1 (DISABLE_INPUT_FILTER): Disable input filter |
