Philips Semiconductors Preliminary User Manual ARM-based Microcontroller LPC2131/2132/2138 RealMonitor enters a loop, polling the DCC. If the DCC read buffer is full, control is passed to rm_ReceiveData() (RealMonitor internal function). If the DCC write buffer is free, control is passed to rm_TransmitData() (RealMonitor internal function). If there is nothing else to do, the function returns to the caller. The ordering of the above comparisons gives reads from the DCC a higher priority than writes to the communications link. RealMonitor stops the foreground application. Both IRQs and FIQs continue to be serviced if they were enabled by the application at the time the foreground application was stopped. RealMonitor 256 November 22, 2004
Philips Semiconductors Preliminary User Manual ARM-based Microcontroller HOW TO ENABLE REALMONITOR LPC2131/2132/2138 The following steps must be performed to enable RealMonitor. A code example which implements all the steps can be found at the end of this section. Adding stacks User must ensure that stacks are set up within application for each of the processor modes used by RealMonitor. For each mode, RealMonitor requires a fixed number of words of stack space. User must therefore allow sufficient stack space for both RealMonitor and application. RealMonitor has the following stack requirements: Table 204: RealMonitor stack requirement IRQ mode A stack for this mode is always required. RealMonitor uses two words on entry to its interrupt handler. These are freed before nested interrupts are enabled. Undef mode A stack for this mode is always required. RealMonitor uses 12 words while processing an undefined instruction exception. SVC mode RealMonitor makes no use of this stack. Prefetch Abort mode RealMonitor uses four words on entry to its Prefetch abort interrupt handler. Data Abort mode RealMonitor uses four words on entry to its data abort interrupt handler. User/System mode RealMonitor makes no use of this stack. FIQ mode RealMonitor makes no use of this stack. Processor Mode RealMonitor Stack Usage (Bytes) Undef 48 Prefetch Abort 16 Data Abort 16 IRQ 8 RealMonitor 257 November 22, 2004
