/* Global Control Registers *************************************************/
|
|
/* Control registers are accessed with the RCR, RBM, WCR, BFS, and BFC
|
|
* commands. The following identifies all ENC28J60 control registers. The
|
|
* control register memory is partitioned into four banks, selectable by the
|
|
* bank select bits, BSEL1:BSEL0, in the ECON1 register.
|
|
*
|
|
* The last five locations (0x1b to 0x1f) of all banks point to a common set
|
|
* of registers: EIE, EIR, ESTAT, ECON2 and ECON1. These are key registers
|
|
* usedin controlling and monitoring the operation of the device. Their
|
|
* common mapping allows easy access without switching the bank.
|
|
*
|
|
* Control registers for the ENC28J60 are generically grouped as ETH, MAC and
|
|
* MII registers. Register names starting with E belong to the ETH group.
|
|
* Similarly, registers names starting with MA belong to the MAC group and
|
|
* registers prefixed with MI belong to the MII group.
