C-bus format to read (slave transmits data)
Table 2
Definition of the transmitted bytes after read condition
Table 3
Function of the bits in Table 2
The master generates an acknowledge when it has received the first data word ALR1, then the slave transmits the next
data word ALR2. Afterwards the master generates an acknowledge, then the slave begins transmitting the first data word
ALR1 etc. until the master generates no acknowledge and transmits a STOP condition.
