73M1903 Data Sheet

DS_1903_032

The bits transmitted on the SDOUT pin are defined as follows:

Bit15 Bit14 Bit13 Bit12 Bit11 Bit10 Bit9 Bit8 Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0

RX15 RX14 RX13 RX12 RX11 RX10 RX9 RX8 RX7 RX6 RX5 RX4 RX3 RX2 RX1 RX0

If the Hardware Control bit (bit 0 of register 01h) is set to zero, the 16 bits that are received on the SDIN

are defined as follows:

Bit15 Bit14 Bit13 Bit12 Bit11 Bit10 Bit9 Bit8 Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0

TX15 TX14 TX13 TX12 TX11 TX10 TX9 TX8 TX7 TX6 TX5 TX4 TX3 TX2 TX1 CTL

In this case TX0=0 is forced.

If the Hardware Control bit (bit 0 of register 01h) is set to one, the 16 bits that are received on the SDIN

input are defined as follows:

Bit15 Bit14 Bit13 Bit12 Bit11 Bit10 Bit9 Bit8 Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0

TX15 TX14 TX13 TX12 TX11 TX10 TX9 TX8 TX7 TX6 TX5 TX4 TX3 TX2 TX1 TX0

Bit 15 is transmitted/received first. Bits RX15:0 are the receive code word. Bits TX15:0 are the transmit

code word. If the hardware control bit is set to one, a control frame is initiated between every pair of data

frames. If the hardware control bit is set to zero, CTL is used by software to request a control frame. If

CTL is high, a control frame will be initiated before the next data frame. A control frame allows the

controller to read or write status and control to the 73M1903.

The control word received on the SDIN pin is defined as follows:

Bit15 Bit14 Bit13 Bit12 Bit11 Bit10 Bit9 Bit8 Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0

R/W A6

The control word transmitted on the SDOUT pin is defined as follows:

Bit15 Bit14 Bit13 Bit12 Bit11 Bit10 Bit9 Bit8 Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0

D7 D6 D5 D4 D3 D2 D1 D0

If the R/W bit is set to a 0, the data byte transmitted on the SDOUT pin is all zeros and the data received

on the SDIN pin is written to the register pointed to by the received address bits; A6-A0. If the R/W bit is

set to a 1, there is no write to any register and the data byte transmitted on the SDOUT pin is the data

contained in the register pointed to by address bits A6-A0. Only one control frame can occur between

any two data frames.

Writes to unimplemented registers are ignored. Reading an unimplemented register returns a value of 0.

The position of a control data frame is controlled by the SPOS; bit 1 of register 01h. If SPOS is set to a 0

the control frames occur mid way between data frames, i.e., the time between data frames is equal. If

SPOS is set to a 1, the control frame is ¼ of the way between consecutive data frames, i.e., the control

frame is closer to the first data frame. This is illustrated in Figure 3.

New to the 73M1903 modem AFE IC is a feature that shuts off the serial clock (SCLK) after 32 cycles of

SCLK following the frame synch (Figure 2). This feature is unavailable in the 20 TSSOP package

option. This mode is controlled by the SckMode pin. If this pin is left open the clock will run

continuously. If SckMode is low the clock will be gated on for 32 clocks for each FS. The SDOUT and FS

pins change values following a rising edge of SCLK. The SDIN pin is sampled on the falling edge of

SCLK. Figure 4 shows the timing diagrams for the serial port.
