Register Descriptions
UT Registers
UT Provisioning Registers (R/W) (continued)
Table 61. Registers 0x020F, 0x0213, 0x0217, 0x021B: Channel [A—D] Receive Provisioning Register (R/W)
Reset default of register 0x020F = 0x0020.
Reset default of register 0x0213 = 0x0120.
Reset default of register 0x0217 = 0x0220.
Reset default of register 0x021B = 0x0320.
*The value 000 for these bits places the corresponding UTOPIA outputs in the high-impedance state.
Table 62. Registers 0x0210, 0x0214, 0x0218, 0x021C: Channel [A—D] Transmit Provisioning Register (R/W)
Reset default of register 0x0210 = 0x0000.
Reset default of register 0x0214 = 0x0120.
Reset default of register 0x0218 = 0x0220.
Reset default of register 0x021C = 0x0320.

U3 configuration also requires the appropriate
setting of register 0x0225 (PA response) to be
set for a two-cycle response.
Polling Enable Transmit Channel [A—D]. If
set, transmit polling mode is enabled.
Reserved. These bits must be written to their
reset default value (00).
Polling Transmit Address Channel [A—D].
Transmit polling address.
Reserved. These bits must be written to their
reset default value (00).
