RESET (bit 7)
This bit sets a software reset. Setting this bit to 1 causes software reset and setting 0 releases it.
TXEN (bit 5)
This bit sets access to the network (online and offline respectively); Setting 1 to this bit is on-line and
setting 0 is off-line. A temporary software reset is applied when the bit is changed from 0 to 1. (The
software reset is released automatically.) The software reset is not applied when the bit is changed from 1
to 0.
This bit is the same as the TXEN bit in the mode register described in 3.2.18, which is the bit usually used.
