Receive Byte Count Low (Read)
RBCL
Together with RBCH (bits RBC11 - RBC8), indicates the length of a received frame
(1 4095 bytes). Bits RBC4-0 indicate the number of valid bytes currently in RFIFO.
These registers must be read by the CPU following a RME interrupt.
Received Byte Count High (Read)
Value after RESET: 000

ISR0
All bits are reset when ISR0 is read.
If bit GCR.VIS is set to ‘1’, interrupt statuses in ISR0 may be flagged although they are
masked via register IMR0. However, these masked interrupt statuses neither generate a
signal on INT, nor are visible in register GIS.

Receive Message End
One complete message of length less than 32 bytes, or the last part
of a frame at least 32 bytes long is stored in the receive FIFO,
including the status byte.
