Field : card_reset | ||||||||||
Hardware reset. 1 Active mode 0 Reset These bits cause the cards to enter pre-idle state, which requires them to be re-initialized. ■ CARD_RESET[0] should be set to 1’b0 to reset card number 0 ■ CARD_RESET[15] should be set to 1'b0 to reset card number 15. The number of bits implemented is restricted to NUM_CARDS. Field Enumeration Values:

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.
