Field : value | |
Controller will read Electronic Signature of devices and populate this field as the number of planes information is present in the signature. For 512B device, this information needs to be programmed by software. Software could also choose to override the populated value. The values in the fields should be as follows[list] [*]3'h0 - Monoplane device [*]3'h1 - Two plane device [*]3'h3 - 4 plane device [*]3'h7 - 8 plane device [*]All other values - Reserved[/list] Field Access Macros: | |

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.
