TTSCNT — Transmit Time-Slot Count
This read-only field indicates the current time-slot number within the transmit frame. This count will
indicate the specific bit of the TSM that is currently active. The value of this field will change with the
transmit word count clock (see Figure 77).
7.4.6 Functional Description
7.4.6.1 General
The SSI has two basic operating modes. Table 51 lists these operating modes and some of the typical
applications in which they can be used. These distinctions result in the basic operating modes that allow the
SSI to communicate with a wide variety of devices. These modes can be programmed by several bits in the
SSI control registers (see Section 7.4.5.2, “Register Descriptions”).
The SSI supports both normal and network modes, and these can be selected independently of whether the
transmitter and receiver are synchronous or asynchronous. Typically, these protocols are used in a periodic
manner, where data is transferred at regular intervals, such as at the sampling rate of an external CODEC.
Both modes use the concept of a frame. The beginning of the frame is marked with a frame sync when
programmed with continuous clock. The frame sync occurs at a periodic interval. The length of the frame
is determined by the DC[4:0] and WL[1:0] bits in either the SRXCR or STXCR register, depending on
whether data is being transmitted or received.
7.4.6.1.1
Normal Mode
Normal mode is the simplest mode of the SSI. It is used to transfer one word per frame. In continuous clock
mode, a frame sync occurs at the beginning of each frame. The length of the frame is determined by the
following factors:
The period of the serial bit clock (PSR, PM[7:0] bits for internal clock or the frequency of the
external clock on the STCK or SRCK pin).
The number of bits per sample (WL[1:0] bits).
The number of time slots per frame (DC[4:0] bits).
Table 51. SSI Operating Modes
TX, RX Sections
1
1. In synchronous mode, the transmitter and receiver use a common clock and frame synchronization signal. In
asynchronous mode, the transmitter and receiver operate independently, on their own clocks and frame syncs.
2. In continuous mode the clocks run all the time. In gated clock mode, the clock operates only when there is data
to exchange.
3. In normal mode, the SSI only transmits during the first time-slot of each I/O frame. In network mode, any number
from 1 to 32 data words of I/O per frame can be used. Network mode is typically used in star or ring time division
multiplex networks with other processors or CODECs, allowing interface to TDM networks without additional
logic.
4. Use of gated clock is not allowed in network mode.
