Notes :
1. When CI signal is tied to low level, NCS signal is the chip select input ; with CI signal at high level, the NCS signal
becomes an output that carry out the logical sum of the following bits : BIT0T, BIT1T.
2. The description of the commands is referred to the system L3030 + LINE INTERFACE module.
3. To set SBY mode with I
lim
= 7mA : BIT0R = 0 and at least one of the two last bits (BIT6R ; BIT7R) must be set to 1.
4. TTX and RING signals are injected into the line interface module with BIT1R to ”1”.
5. To set RING mode at least one of the three last bits (BIT5R, BIT6R, BIT7R) must be set to 1, in addition BIT0R
must be set to 0.
6. The description of the commands is referred to the system L3030 + LINE INTERFACE module.
7. The bit BIT2T is set to 1 when the SLIC is operating in Conversation Mode and into the limiting current region (short
loop).
8. The bit BIT4T is set to 1 when the junction temperature of L3000N is about 140
°
C.
