When a microcontroller is used that implements an I
the I
data and FSK-data from the PCD3316 takes 48 bits on the I
baud rate of 1200 (corresponds to 1200 bits per second) the minimal speed of the
I
PCD3316 will cause the processor to collect extra information from the PCD3316.
As a consequence, the FSK-data can be overrun in the PCD3316 and one data byte
will be lost. In this case, the time base interrupt should be suppressed while FSK is
active. This can be done by setting the ‘INT-SUP on/off’ bit (bit 4 in Mode register 2).
The ‘TB on/off’ bit (bit 6 in Mode register 2) will still be set but the IRQ output will not
be activated by the time base interrupt. Any time base interrupt can be detected by
the microcontroller when an FSK interrupt is processed by reading the Interrupt
register.

C-bus should be 5.76 kbits/s. Additional interrupts generated by the time base of the

C-bus can be critical during reception of FSK. The collection of the interrupt
