STM8SPLNB1 operation
STM8SPLNB1 has 8 output pins which can work as 4 I2C master channels. Each I2C
channel can address 2 LNB devices (2 different I2C addresses: 0xC8 and 0xCA) - see
Table 2: SaTCRs implementation - ST7LNB1 compatible mode and Table 3: SaTCRs
implementation - incremental order mode for assignment of given SaTCR to given I2C bus
and address.
Assignment depends from I2C addressing mode EEPROM parameter - see Table 14:
STM8SPLNB1 EEPROM parameters. As a convention, SaTCR1 must be associated to the
BPF having the lowest center frequency of the application, SaTCR2 to the BPF having the
next higher center frequency and so on.

1. Selection of ST7LNB1 compatible mode: pin MODE (see Table 1: STM8SPLNB1 pins description) must be
grounded and I2C addressing mode EEPROM parameter (see Table 14: STM8SPLNB1 EEPROM
parameters) must be set to 0. Otherwise (e.g. pin MODE is left open or I2C addressing mode EEPROM
parameter is set to 1) is used incremental order mode.
