CCP1 F452 Module Inquiry

[chingB]

Hello,

I found out that in the F452.H header file particularly the line stated below:
long CCP_1;
#byte CCP_1 = 0xfbe
#byte CCP_1_LOW= 0xfbe
#byte CCP_1_HIGH= 0xfbf

Why is that CCP_1 was declared as a 16bit variable? I try to look at the F452 data sheet and found-out that 0xFBE register address for CCP_1 is an 8bit register?

One more thing CCP_1_LOW has the same address with CCP_1 which is of different data types. I understand that CCP_1_LOW is an 8bit register.

With this the declaration long CCP_1 only uses the lower 8bit rather than the 16bit lval.

Is their another way of defining and using the CCP_1 such that it can be easily ported to other C Compiler?

Anyone can explain it why this is so?

Thnx

Read section 14.3 Capture Mode of the 18F452 data sheet.
Read the first sentence in that section.

The CCP register is composed of 2 bytes. A low byte and a high byte. The 16 bit variable is so you can assign the by a 16 value rather than a having to do 2 8bit assignments. It is correct BTW.

I want to change the definition of the line stated below <w/o using #byte>:
