7.10.19.4.1 GSMR Programming. The GSMR programming sequence is as follows:
1. The MODE bits should be set to AppleTalk.
2. The ENT and ENR bits should be set.
3. The DIG bits should be set for normal operation, with the CD and CTS pins
4. The RDCR and TDCR bits should usually be set to 16x clock.
5. The TENC and RENC bits should be set for FM0.
6. The Tend bit should be zero.
7. The TPP bits should be 11.
8. The TPL bits should be set to 000 to transmit the next frame with no
9. The TINV and RINV bits should be zero.
10. The TSNC bits should be set to 1.5 bit times 10.
11. The EDGE bits should be zero.
12. RTSM should be zero.
13. All other bits should be set to zero or to their default condition.

synchronization sequence and to 001 to transmit the next frame with
the LocalTalk synchronization sequence. For example, data frames do
not require a preceding synchronization sequence. These bits may be
modified on the fly if the AppleTalk protocol is selected.
