Detailed Description

Definition of the register linked to a particular channel when SPAGE=0.

The channel registers are further splitted into two groups. This first group is defined when the Global register WKREG_SPAGE is 0

-------------------------------------------------------------------------

Warning: The received buffer can hold 256 bytes. However, as the RFCNT reg is 8 bits, if we have 256 byte in the register this is reported as 0 ! Therefore RFCNT=0 can indicate that there are 0 or 256 bytes in the buffer. If we have RFDAT = 1 and RFCNT = 0 it should be interpreted as 256 bytes in the FIFO.

Note: Note that in case of overflow the RFOE goes to one but as soon as you read the FSR this bit is cleared. Therefore Overflow can be read only once.
The same problem applies to the transmit buffer but here we have to check the TFFULL flag. So if TFFULL is set and TFCNT is 0 this should be interpreted as 256
