01 to 07 Not used.
08 Peripheral Port Reset Bit
Turn ON to reset peripheral port. (Not valid when peripheral device is connected.) Auto-
matically turns OFF when reset is complete.
94
09 RS-232C Port Reset Bit
Automatically turns OFF when reset is complete.
10 PC Setup Reset Bit
Turn ON to initialize PC Setup (DM 6600 through DM 6655). Automatically turns OFF
again when reset is complete. Only effective if the PC is in PROGRAM mode.

11 Forced Status Hold Bit
OFF: The forced status of bits that are forced set/reset is cleared when switching
between PROGRAM mode and MONITOR mode.
ON: The status of bits that are forced set/reset are maintained when switching between
PROGRAM mode and MONITOR mode.

SR 253 00 to 07 FAL Error Code
The error code (a 2-digit number) is stored here when an error occurs. The FAL number is
stored here when FAL(06) or FALS(07) is executed. This word is reset (to 00) by execut-
ing a FAL 00 instruction or by clearing the error from a Peripheral Device.
