To manually start RT2 after soft reset completion (indicated by READY signal assertion), the host must set RT2STEX
bit 5 in register 0x0000, if RT1 auto-start was disabled or otherwise failed for one or more of these reasons:
23.3. Bus Monitor SMT / IMT
This is initiated when MTRESET bit 12 is set in the Master Status and Reset Register 0x0001. The following actions
are performed.

Loads these registers from EEPROM
The RT2ENA pin was logic 0 during the soft reset event
The RT2ENA pin was logic 0 and/or RT2ENA bit 7 was logic 0 in the Master Configuration Register when
EECOPY created the EEPROM image. A new EEPROM image is needed to allow auto-start after RT2 soft reset.
The RT2STEX bit 5 is logic 0 in the EEPROM Master Configuration Register image because the unlock codes
used by EECOPY were wrong. A new EEPROM image is needed to allow auto-start after RT2 soft reset.
