Yes.

>> However the SPM_PAGESIZE defines the flash page size in words instead of bytes for the at90pwm3b and at90pwm2b part.


Comparing other device header files with corresponding datasheets shows that SPM_PAGESIZE represents number of bytes per page. However in the case of io90pwm2b/3b, SPM_PAGESIZE was probably given in words as 32.

I have corrected it to 64. Patch attached for review.

The API Usage example for <avr/boot.h> implies that SPM_PAGESIZE is defined in bytes, not words.

However the SPM_PAGESIZE defines the flash page size in words instead of bytes for the at90pwm3b and at90pwm2b part.

According to the AT90PWM2/3/2B/3B datasheet, Section 24.7.13 Boot Loader Parameters (pg 278) the number of bytes in a page is 64.
