Limits of Indirect Approach Through FSR in PIC16
Friends, today while writing a programme for the LCD I got the below message upon compilation. The built was fine, but with a warning that the IRP bit must be set manually for a specific message.
And if I run this programme on the microcontroller, then the display messages are random and anonymous.
The IRP bit is used for the bank selection in the microcontroller though indirect addressing.
I went through the datasheet and the MicroE compiler help section and found the solutions that to make the programme run prefect on the microcontroller in indirect addressing mode
- · The IR bit must be set manually for the bank selection
- · Reduce the message size so that ROM used is lower
- · At last switch to PIC 18FXX
