NOTES:
1. TEST1, TEST2, TEST3 and TEST4 registers are used by the factory; these registers must be cleared (set to 00h) on power–
up initialization to insure proper operation.
2. Register banks Axh, Bxh, Cxh, Dxh, Exh, and Fxh are not accessible.
3. Upper nibble of the PCVCR1 register is used for MOSCR1
6. CONTROL, ID, AND TEST REGISTERS
The operation of the DS21352/552 is configured via a set of eleven control registers. Typically, the
control registers are only accessed when the system is first powered up. Once the DS21352/552 has been
initialized, the control registers will only need to be accessed when there is a change in the system
configuration. There are two Receive Control Registers (RCR1 and RCR2), two Transmit Control
Registers (TCR1 and TCR2), and seven Common Control Registers (CCR1 to CCR7). Each of the eleven
registers are described in this section.
6.1 POWER-UP SEQUENCE
On power–up, after the supplies are stable the DS21352/552 should be configured for operation by
writing to all of the internal registers (this includes setting the Test Registers to 00h) since the contents of
the internal registers cannot be predicted on power–up. The LIRST (CCR7.7) should be toggled from
zero to one to reset the line interface circuitry (it will take the DS21352/552 about 40ms to recover from
the LIRST bit being toggled). Finally, after the TSYSCLK and RSYSCLK inputs are stable, the ESR bit
should be toggled from a zero to a one (this step can be skipped if the elastic stores are disabled).
6.2 DEVICE ID
There is a device IDentification Register (IDR) at address 0Fh. The MSB of this read–only register is
fixed to a zero indicating that a T1 device is present. The next 3 MSBs are used to indicate which T1
device is present; DS2152, DS21352, or DS21552. The E1 pin–for–pin compatible SCTs will have a
logic one in the MSB position with the following 3 MSBs indicating which E1 SCT is present; DS2154,
DS21354, or DS21554. Table 6-1 represents the possible variations of these bits and the associated SCT.
