about the NIOS II IDE

About the Address of the TIMER_CONTROL and TIMER_STATUS: in my SOPCBUILD, the TIMER_0_BASE = 0x4800(18432) So ,I think the address: TIMER_CONTROL: 0x4800(18432)+2 = 0x4800(18432)+2 ...

Hi xc214043,

> But one the DISASSEMBLY , I find the TIMER_CONTROL`s address if 18436(0x4800+4)

This is correct ... the registers are all 32-bit aligned.

status @ base + 0x00

control @ base + 0x04

periodl @ base + 0x08

and so on.
