ARCNET_EXTND

typedef struct s_ARCNET_EXTND {
    unsigned char   z_ckup_0;
    unsigned char   z_ckup_1;

    unsigned char   z_rcntm_0;
    unsigned char   z_rcntm_1;

    // reserved for future use
    unsigned char   z_receiveall;    // Do NOT use or modify!!
    unsigned char   b_reserved[11];  // Do NOT use or modify!!
} ARCNET_EXTND;
 

This structure is only required for use with 20022, 20020C and 20019 controllers.

The above mentioned items correspond directly with the bits in the controllers registers.
z_ckup_x sets the clock multiplier.
z_rcntm_x sets the reconfiguration timeout.

For more information on the above mentioned items, refer to the ARCNET-controllers datasheets, that are available from SMSC (www.smsc.com). You can also order data sheets from SoHard. It is strongly recommended, that you are familiar with ARCNET and the used ARCNET-controller.
