GPIO Port
The CYBLE-0130XX-00 has 14 general-purpose I/Os (GPIOs) in the 32-pin package. All GPIOs support programmable pull-up and
pull-down resistors, and all support a 2 mA drive strength except P26, P27, and P28, which provide a 16 mA drive strength at 3.3V
supply. The following GPIOs are available:
n P0-P4
n P8/P33 only available for CYBLE-013030-00
n P11/P27 (Dual bonded, only one of two is available.)
n P12/P26 (Dual bonded, only one of two is available.)
n P13/P28 (Dual bonded, only one of two is available.)
n P14/P38 (Dual bonded, only one of two is available.)
n P15
n P24
n P25
n P32 - only available for CYBLE-013030-00
For a description of all GPIOs, see
