Data Structure Documentation

struct ALT_I2C_CLR_RD_REQ_s

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
