AT90USB64/128
ALE is the external data memory Address latch enable.
HWB allows to execute the bootloader section after reset when tied to ground during external
reset pulse. The HWB mode of this pin is active only when the HWBE fuse is enable.
• RD – Port E, Bit 1
RD is the external data memory read control enable.
• WR – Port E, Bit 0
WR is the external data memory write control enable.
