HIDRIVE=STANDARD, HS=ENABLED, FUNC=PIO0_2
I/O configuration register for pin PIO0_2/SCL/ACMP_O/ TCK/SWCLK/ CT16B0_CAP0
FUNC | Selects pin function for pin PIO0_2/SCL/ACMP_O/ TCK/SWCLK/ CT16B0_CAP0 0 (PIO0_2): 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 (SCL): I2C-bus clock (true open-drain) input/output. Input glitch filter (50 ns) capable. 2 (ACMP_O): Analog comparator output. 3 (TCK_SWCLK): Serial Wire Debug Clock (secondary for LQFP and HVQFN packages). Input glitch filter (50 ns) capable. For the WLCSP20 package only, this pin is configured to the SWCLK function by the boot loader after reset. 4 (CT16B0_CAP0): Capture input 0 for 16-bit timer 0.Input glitch filter (50 ns) capable. |
