EMB AND ERB INITIALIZATION VALUES
The EMB and ERB flag bits are set automatically by the values of the RESET vector address and the interrupt vector
address. When a RESET is generated internally, bit 7 of program memory address 0000H is written to the EMB
flag, initializing it automatically. When a vectored interrupt is generated, bit 7 of the respective vector address table
is written to the EMB. This automatically sets the EMB flag status for the interrupt service routine. When the
interrupt is serviced, the EMB value is automatically saved to stack and then restored when the interrupt routine has
completed.
At the beginning of a program, the initial EMB and ERB flag values for each vectored interrupt must be set by using
VENT instruction. The EMB and ERB can be set or reset by bit manipulation instructions (BITS, BITR) despite the
current SMB setting.

The following assembly instructions show how to initialize the EMB and ERB flag settings:
