Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
I2C0 Clock Gating Control. This bit controls the clock gating for I2C
module 0. If set, the unit receives a clock and functions. Otherwise, the
unit is unclocked and disabled. If the unit is unclocked, reads or writes
to the unit will generate a bus fault.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
SSI1 Clock Gating Control. This bit controls the clock gating for SSI
module 1. If set, the unit receives a clock and functions. Otherwise, the
unit is unclocked and disabled. If the unit is unclocked, reads or writes
to the unit will generate a bus fault.
SSI0 Clock Gating Control. This bit controls the clock gating for SSI

module 0. If set, the unit receives a clock and functions. Otherwise, the
unit is unclocked and disabled. If the unit is unclocked, reads or writes
