SYNTAX      [<LABEL>] BANZ <pma>[,{ind}[,<next ARP>]]

OPERANDS    0 . pma . 65535; 0 . next ARP . 7.

EXECUTION   If AR(ARP) is not equal to 0:
            pma . PC; else (PC) + 2 . PC
            Modify AR(ARP) and ARP as specified.

DESCRIPTION Control is passed to the designated program memory address
            (pma) if the current auxiliary register is not equal to zero.
            Otherwise, control passes to the next instruction. The current
            auxiliary register and ARP are also modified as specified.

            The current auxiliary register is either incremented or
            decremented from zero when the branch is not taken. Note that
            the AR modification defaults to *- (decrement the current AR
            by one) when nothing is specified, making it compatible with
            the TMS320C1x. Pma can be either a symbolic or numeric
            address.

            BANZ designed for loop control using the auxiliary registers
            as loop counters. Using *0+ or *0- allows modification of the
            loop counter by a variable step size. Care must be exercised
            when doing this because the auxiliary registers behave as
            modulo 65536 counters and zero may be passed without being
            detected if AR0 > 1.
