how to simulate special registers in ARM Core

Pepoja

Hi all,

I have a problem.

I can simulate my application (C and Keil uVision5). Target: LPC824
But, simulator stopped at one line: wait for PLL Locked.

After change PLL control register (SYSPLLCTRL), application must wait while bit LOCK in SYSPLLSTAT register is zero. In realtime debugging in target working fine, but in simulator don't work - SYSPLLSTAT don't changed.

Please, How to simulate changes in SYSPLLSTAT register (this is read-only register)?

LPC82x User's manual: www.nxp.com/.../UM10800.pdf - see 5.6.4 on page 35

Thank you.

peter
