This is a shadow register for the FIFO enable bit [0] of register FCR.
Register Layout
Bits | Access | Reset | Description |
---|---|---|---|
[0] | RW | 0x0 | Shadow FIFO Enable |
[31:1] | ??? | 0x0 | UNDEFINED |
Field : Shadow FIFO Enable - sfe | ||||||||||
This can be used to remove the burden of having to store the previously written value to the FCR in memory and having to mask this value so that only the FIFO enable bit gets updated. This enables/disables the transmit (Tx) and receive (Rx ) FIFO's. If this bit is set to zero (disabled) after being enabled then both the Tx and Rx controller portion of FIFO's will be reset.

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.
