174 of 366
The Port[n]_stat_reg1 regi
ster has real-time (not latched) status fields. The index n indicates port number: 1-8 for
DS34T108, 1-4 for DS34T104, 1-2 for DS34T102, 1 only for DS34T101.

Description
[31:25] Reserved - 0x0 Must be set to zero
[24] Smart_disabled RO 0x0 not documented
[23:5] DPLL_level RO 0x0 not documented
[4:2] Adapt_current_state RO 0x0
Port n clock recovery current state:
0 = Idle

[1] RTS RO 0x0
When the Port[n]_cfg_reg.Int_type field specifies a serial
interface, the value of the TDMn_RSIG_RTS pin--
which
behaves as RTS (Request To Send)—can be read from
this bit.
[0] TSA_int_act_blk RO 0x0
Indicates which bank is active:
0 = Port n TSA bank1 is active
1 = Port n TSA bank2 is active
The Port[n]_stat_reg2 regi
ster has real-time (not latched) status fields. The index n indicates port number: 1-8 for
DS34T108, 1-4 for DS34T104, 1-2 for DS34T102, 1 only for DS34T101.

11.4.2 Bundle Configuration Tables
The base address for the TDMoP bundle configuration tables is 0x8,000. Bundle configurations are 160 bits long
and therefore span five 32-bit words. The least-significant 32-bit word of a bundle configuration is located at
address offset 0x000 + BundleNumber x 4. The most-significant 32-bit word is located at address offset 0x400 +
BundleNumber x 4. There are 64 bundles numbered 0 to 63. In the register descriptions in this section the index n
indicates bundle number: 0 to 63.
Each bundle can be one of three different types: AAL1, HDLC or SAToP/CESoPSN. Subse
ctions 11.4.2.1 through
11.4.2.3 de
scribe the bundle configuration fields for each of the four types. Some fields are common to two or more
of the bundle types. The payload type is specified in the Payload_type_machine field, bits 21:20 of
xxxx_Bundle[n]_cfg[63:32].
11.4.2.1 AAL1 Bundle Configuration
In the register descriptions below, the index n indicates the bundle number: 0 to 63.
