I/O configuration register for pin PIO0_3/SDA/ACMP_O/ SWDIO/CT16B1_CAP0
FUNC | Selects pin function for pin PIO0_3/SDA/ACMP_O/ SWDIO/CT16B1_CAP0 0 (PIO0_3): General purpose digital input/output pin. High-current sink (20 mA) or standard-current sink (4 mA) programmable; true open-drain for all pin functions. Input glitch filter (50 ns) capable. 1 (SDA): I2C-bus data (true open-drain) input/output. Input glitch filter (50 ns) capable. 2 (ACMP_O): Analog comparator output. 3 (SWDIO): Serial Wire Debug I/O (secondary for LQFP and HVQFN packages). Input glitch filter (50 ns) capable. For the WLCSP20 package only, this pin is configured to the SWDIO function by the boot loader after reset. 4 (CT16B1_CAP0): Capture input 0 for 16-bit timer 1. Input glitch filter (50 ns) capable. |
