BCNT
Buffer Byte Count is the length of the buffer pointed to by this descriptor expressed
in two’s complement. This field is written to by the Host and unchanged by MK50H28.
The value of BCNT must be an even number. For LMI channels this field should be set to
greater than 14 bytes.

BIT
NAME
DESCRIPTION
15:00
MCNT
Message Byte Count is the length, in bytes, of the received signal unit. MCNT is valid
only when ELF is set to a one. MCNT is written by MK50H28 and read by the Host. If
ELF is set to a zero the entire buffer has been utilized and the message byte count is
given in BCNT above. The value of this field is expressed in two’s complement.
