Reading the Trace Memory Window
Reading the information in the trace memory window requires knowledge of device
architecture. PICmicro MCU instructions fetch one instruction cycle while decoding and
executing the previous cycle, (i.e., there is a one cycle pipeline).
In the example below:
1. At line 2, the W register (address = 0xfe8) is cleared.
2. The next cycle, the value gets written into the W register, i.e., the W register value
of 0xFF is changed to 0x00.

REAL-TIME READS
This feature consists of a real-time read buffer that records the data of all processor file
register write operations. The address and data are obtained from the file register
address and data bus. The write operation to the real-time read buffer occurs after data
buffers have latched the information from the file register address and data bus.
The real-time display (either Watch, File Register or SFR window) gives a dynamic
display of data, which is being continuously captured in real time. The values displayed
are the values that are collected from the last read of the real-time read buffer. The time
interval between real-time reads is set up under the Debugger>Settings , View tab.
DS51490A-page 56
Note:
A longer time interval than the default value will update the values at a
much slower pace, making it easier to monitor values.
