FIFO input HDLC frame counter (F1)
Up to 7 HDLC frames can be stored in each FIFO.
FIFO output HDLC frame counter (F2)
Up to 7 HDLC frames can be stored in each FIFO.
FIFO input counter (Z1)
Up to 128 bytes can be stored in one FIFO so the maximum
value of the Z1 counter is 7Fh.
FIFO output counter (Z2)
Up to 128 bytes can be stored in one FIFO so the maximum
value of the Z2 counter is 7Fh.

'0000' 0 bytes
'0001' 8 bytes (reset default)
:
'1111' 120 bytes
The corresponding bit(s) in the F_FILL register are set if the
number of bytes in a transmit FIFO is greater or equal than this
value.

and PCM-receive (see also F_FILL)
'0000' 0 bytes
'0001' 8 bytes (reset default)
:
'1111' 120 bytes
The corresponding bit(s) in the F_FILL register are set if the
number of bytes in a receive FIFO is greater or equal than this
value.
