GPIO Ports
The BCM20706 embedded package has 24 general-purpose I/Os (GPIOs) in a 49-pin package. All GPIOs
support programmable pull-ups and are capable of driving up to 8 mA at 3.3V or 4 mA at 1.8V, except P26, P27,
P28, and P29, which are capable of driving up to 16 mA at 3.3V or 8 mA at 1.8V.

I2S_PCM_OUT/P3/P29/P35 (quadruple bonded; only one of four is available)
I2S_PCM_CLK/P2/P28/P37 (quadruple bonded; only one of four is available)
I2S_WS_PCM_SYNC/P0/P34 (triple bonded; only one of three is available)
All of these pins can be programmed as ADC inputs.
Port 26–Port 29
P[26:29] consists of four pins. All pins are capable of sinking up to 16 mA for LEDs. These pins also have PWM
functionality, which can be used for LED dimming.
