I wouldn't be so sure. Like PICs, the ATmega644P is an 8-bit device. Max. clock speed is 20 MHz. Some high end PICs can run @ 40 MHz. The TT3+ used a mid-range PIC (16F series), which probably wouldn't be up to the task of decoding, & at the assembly level the mid & high range PICs aren't code-compatible, so porting code from the mid-range probably wouldn't be any easier between the high-end PICs & the Atmel.
