23.2. Remote Terminal 2 (RT2)
This is initiated when RT2RESET bit 11 is set in the Master Status and Reset Register 0x0001. The following actions
are performed.
RT2 automatically starts (RT2STEX is set in register 0x0000) after soft reset completion, if these requirements are
met:
•
•

Terminal Checksum stored at 0x01E0 by

Clears these entire register addresses
EECOPY created the EEPROM image. A new EEPROM image is needed to allow auto-start after RT1 soft reset.
The RT1STEX bit 4 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 RT1 soft reset.
The RT2ENA pin is logic 1 during the soft reset event
The RT2ENA pin and RT2ENA bit 7 were both logic 1 in the Master Configuration Register when EECOPY
created the EEPROM image.
The RT2STEX bit 5 is logic 1 in the EEPROM Master Configuration Register image because the EECOPY unlock
codes during programming were Unlock Word 1 = 1010-XXXX-11XX-1010 and Unlock Word 2 = 0101-XXXX-
00XX-0101 where X denotes “don’t care”.
