Memory Page Controller Registers
: The Code Page Register contains the value for the
current 32K-word Code page. See Figure 18 for bit field
assignments.
: The Index Page Register extends the Index Register
) by 5 bits; i.e., when a Subroutine Return is performed,
contains the Code page from which the subroutine
was called, and comprises the 5 most significant bits of the
top element of the Return Stack. See Figure 19. During
nonsubroutine operation, writing to
Code page value to be written to
directly to
does not push the Return Stack.
