I would like to use timer3 in the PIC 18F452 as an 8bit timer. I cleared the RD16 of the T3CON register.
The datasheet says
So it looks like I cannot assume that clearing this bit will let me work with this timer as an 8 bit timer such that an interrupt is generated when the 8th bit overflows. Am I correct? How do I use the timer 3 as an 8 bit timer? Is it possible at all?
Please help
The datasheet says
datasheet said:bit 7 RD16: 16-bit Read/Write Mode Enable bit
1 = Enables register Read/Write of Timer3 in one 16-bit operation
0 = Enables register Read/Write of Timer3 in two 8-bit operations
