# parameter must be provided.
# SAMD SERCOM configuration to specify which pins to use on a given SERCOM.
# One may define one section with the "samd_sercom" prefix per
# SERCOM available. Each SERCOM must be configured prior to using it as
# SPI or I2C peripheral. Place this config section above any other section
# that makes use of SPI or I2C buses.

#tx_pin:
# MOSI pin for SPI communication, or SDA (data) pin for I2C
# communication. The pin must have a valid pinmux configuration
# for the given SERCOM peripheral. This parameter must be provided.
#rx_pin:
# MISO pin for SPI communication. This pin is not used for I2C
# communication (I2C uses tx_pin for both sending and receiving).
# The pin must have a valid pinmux configuration for the given
# SERCOM peripheral. This parameter is optional.
#clk_pin:
# CLK pin for SPI communication, or SCL (clock) pin for I2C
# communication. The pin must have a valid pinmux configuration
# for the given SERCOM peripheral. This parameter must be provided.
# Statically configured AD5206 digipots connected via SPI bus (one may
# define any number of sections with an "ad5206" prefix).
