Note 1: The device ID register and the system clock-interface control register exist in Transceiver 1 only (TS0, TS1 = 0).
Note 2: Only the factory uses the test register; this register must be cleared (set to all zeros) on power-up initialization to ensure proper
operation.
8. CONTROL, ID, AND TEST REGISTERS
The DS21Q58 operation is configured through a set of nine control registers. Typically, the control registers are
only accessed when the system is first powered up. Once the device has been initialized, the control registers only
need to be accessed when there is a change in the system configuration. There is one receive control register
(RCR), one transmit control register (TCR), and seven common control registers (CCR1 to CCR7). Each of these
registers is described in this section.
Address 0Fh has a device identification register (IDR). The four MSBs of this read-only register are fixed to 1 0 0 1,
indicating that a DS21Q58 E1 quad transceiver is present. The lower 4 bits of the IDR are used to identify the
revision of the device. This register exists in Transceiver 1 only (TS0, TS1 = 0).
The factory in testing the DS21Q58 uses the test register at addresses 1E. On power-up, the test register should
be set to 00h for the DS21Q58 to properly operate.
