Section 37. “Timer Counter (TC)”
TIOA1 replaced with TIOB1 in Section 37.1 “Description” and added a note for ENETRG description in Section
37.7.3 “TC Channel Mode Register: Waveform Mode”.
Erroneous description of TCCLKS table, rows 0 to 4 reworked in Section 37.7.2 “TC Channel Mode Register:
Capture Mode” and Section 37.7.3 “TC Channel Mode Register: Waveform Mode”
Section 37.7.14 “TC Block Mode Register”: corrected TC2XC2S field configuration values: value 2 is TIOA0 (was
TIOA1); value 3 is TIOA1 (was TIOA2)
Section 7.2 “16-bit Counter”, Section 7.12.1 “WAVSEL = 00”, Figure 37-9 “WAVSEL = 10 without Trigger”, Figure 37-
10 “WAVSEL = 10 with Trigger”, Section 37.6.11.3 “WAVSEL = 01”, and Figure 37-14 “WAVSEL = 11 with Trigger”:
replaced “0xFFFF” with “
2
n
-1” in first paragraph (with “n” representing counter size)
Section 38. “High Speed MultiMedia Card Interface (HSMCI)”
Changed PDCFBYTE to FBYTE in Section 9.6 “WRITE_SINGLE_BLOCK/WRITE_MULTIPLE_BLOCK Operation
using DMA Controller” and in Section 9.8 “READ_SINGLE_BLOCK/READ_MULTIPLE_BLOCK Operation using
DMA Controller”.
Section 14. “Register Write Protection”: changed title (was “Write Protection Registers”); revised content
In Section 15.2 “HSMCI Mode Register”, PDCMODE bit description, corrected reference to MCI Mode Register to
HSMCI Status Register.
In Section 15.7 “HSMCI Block Register”, BLKLEN bit description, removed sentence on its accessibility in HSMCI
Mode Register.
Section 15.18 “HSMCI Write Protection Mode Register”: modified register name (was HSMCI Write Protect Mode
Register); replaced list of protectable registers with cross-reference to section “Register Write Protection”

(1)
.
Section 40.4.2 “Power Management”: added detail on fast RC.
Changed register names:
Section 40.7.10 old: UDP Endpoint Control and Status Register (Control, Bulk Interrupt Endpoints),
new: ”UDP Endpoint Control and Status Register (CONTROL_BULK)”
Section 40.7.11 old: UDP Endpoint Control and Status Register (Isochronous Endpoints), new:
”UDP Endpoint Control and Status Register (ISOCHRONOUS)”.
Section 41. “Analog Comparator Controller (ACC)”
Section 41.1 “Description” Updated section for clarity.
