True or False, thanks

1. On ZYNQ, all 32 bits of the ARM address bus are brought off-chip to address external memory 2. One gigabyte of DDR is included as an IP block on the ZYNQ chip 3. In a RISC machine, one ALU operand must come from a register, and one can come from external memory 4. You can write an ARM shift instruction that will not execute if the previous result was negative 5. An ARM branch instruction target address can be anywhere in the entire 232 address space 6. In a two-address machine, one operand location must also serve as the destination 7. Six bits in the lower word of an ARM instruction define conditional execution settings for the instruction 8. The S bit in the ARM opcode is used to determine whether a conditional instruction is executed 9. The ARM has 16 registers, but only 13 of them are typically used for general data storage 10. The link register cannot be modified by ARM instructions 11. ARM defines an ascending stack 12. All ARM opcodes set aside 12 bits to be used for immediate values 13. In ARM, the AMBA bus is used to connect peripheral IP blocks to the processor
