Transmit Data Pointer: This 32-bit pointer contains the start address of the transmit data
User’s Manual
FNUM = k means that after the current frame k + 1 characters are sent
(k + 1) times 7E

(k + 1) times 00
(k + 1) times TFLAG
(k + 1) times FF
For HDLC mode FNUM is reduced by one eight of the number of zero
insertions if FA is set. If the reduction would result in a negative number of
interframe time-fill characters it is set to 0.

section. Although MUNICH32 works only long word oriented, it
is possible to begin a transmit data section at an uneven
address. The two least significant bits (ADD) of the transmit data
pointer determine the beginning of the data section and the
number of data bytes in the first long word of the data section,
respectively.
MUNICH32 reads the first long word and discards the unused
least significant bytes. The NO establishes (determines) the end
of
I (NO ADD)
long word of the data section.
MUNICH32 reads the last long word and discards the unused
most significant bytes of the last long word.
If the first access is the same as the last access, ADD specifies
the beginning of the data section and NO the number of data
bytes in the long word. All unused bytes are discarded.
