Summary: iom32u4.h defines non-existing TIMSK2 and TIMSK5

Details:

The 32u4 does not have a timer2 or timer5, but the include file does define
TIMSK2 and TIMSK5 (I double-checked the register map, these registers really
don't exist). It seems that the other timer-related registers for these timers
are not defined as expected.

This bug still exists in trunk (checked r2478).

Update of bug #45539 (project avr-libc):

Status: None => In Progress
Assigned to: None => pitchumani
Summary: iom32u4.h defines non-existing TIMSK2 and TIMSK5 =>
iom32u4.h defines reserved IO address (TIMSK2 (0x70), TIMSK5 (0x73) etc)

_______________________________________________________

Follow-up Comment #1:

iom32u4.h incorrectly defines following IO addresses:

PCMSK1 (0x6C) and PCMSK2 (0x6D) are reserved
TIMSK2 (0x70) and TIMSK5 (0x73) are reserved
Registers from 0x9E to 0xB7 are reserved
Registers from 0xD5 to 0xD6 are reserved
Registers from 0xDB to 0xDF are reserved
Register 0xE7 is reserved
Registers from 0xF5 to 0xF9 are reserved
