pins respectively. When the SB3 pins of Channel 1 to Channel 4 are configured as outputs, the control data is written to these four SB3
pins via the SB3[0] to SB3[3] bits respectively.
GREG13: FSK Flag Length, Read/Write (2CH/ACH)
The flag signal is a stream of ‘1’ which is transmitted between two message bytes during Caller-ID messages transmission. The Flag
Length bits FL[7:0] determine the number of the flag bits. The flag length can be from 0 to 255 (d) bits. The default flag length is 0 (i.e.
FL[7:0] = 00H), which means that no flag signal will be transmitted.
GREG14: FSK Data Length, Read/Write (2DH/ADH)
The Data Length bits DL[7:0] determine the number of the data bytes that will be transmitted except the flag signal. The data length can
be from 0 to
64 (d) bytes. Any value larger than 64 (d) in this register will be taken as 64 (d) by the CODEC. The default data length is 0
(d), which means that no data bytes will be transmitted.
GREG15: FSK Seizure Length, Read/Write (2EH/AEH)
The Seizure Length is the number of ‘01’ pairs that represent the seizure phase. The Seizure Length is two times of the value of the
SL[7:0] bits. The value of the SL[7:0] bits can be from 0 to 255 (d), corresponding to Seizure Length of 0 to 510 (d). The default value is
0 (d), which means that no seizure signal will be transmitted.
GREG16: FSK Mark Length, Read/Write (2FH/AFH)
The Mark Length bits ML[7:0] determine the number of the mark bits of ‘1’, which is transmitted in initial flag phase. The Mark Length can
be from 0 to 255 (d). The default value is 0 (d), which means that no mark signal will be transmitted.
GREG17: FSK Start, Mark After Send, BT/Bellcore Selection, FSK Channel Selection and FSK On/Off, Read/Write (30H/B0H)
The FSK Channel Select bits (FCS[1:0]) select a channel on which the FSK signal is generated.
FCS[1:0] = 00:
Channel 1 is selected (default);
FCS[1:0] = 01:
Channel 2 is selected;
FCS[1:0] = 10:
Channel 3 is selected;
FCS[1:0] = 11:
Channel 4 is selected.
The FSK On/Off bit (FO) enables or disables the FSK function block.
FO = 0:
The FSK function block is disabled (default);
