PMC:
Section 30.1.4.2 “Slow Clock Crystal Oscillator”, replaced “...in MOSCSEL bit of CKGR_MOR,...” with “...in XTALSEL bit of
SUPC_CR,...” in the last phrase of the 3d paragraph.
Section 30.1.4.2 “Slow Clock Crystal Oscillator”, added references on the OSCSEL bit of PMC_SR in the 3d paragraph.
Register names in Clock Generator: Replaced “PLL_MCKR” with “PMC_MCKR” and “PLL_SR” with “PMC_SR” in Section
30.1.5.5 “Software Sequence to Detect the Presence of Fast Crystal”.
In Section 30.1.6.1 “Divider and Phase Lock Loop Programming”, 3rd bullet, replaced PMC_IER with PMC_SR. Deleted
previous 4th bullet (was useless sentence “
Disable and then enable the PLL...”).
In
Figure 30-3 “Main Clock Block Diagram” and Section 30.1.5.3 “3 to 20 MHz Crystal or Ceramic Resonator-based
Oscillator” paragraph 5, replaced MOSCXTCNT with MOSCXTST.
Added code example in step 1. of Section 30.2.13 “Programming Sequence”.
Corrected reset value of CKGR_MOR register in Table 30-2, “Register Mapping”.
USART:
In Table 37-10 “Maximum Timeguard Length Depending on Baud Rate” and in Table 37-11 “Maximum Time-out Period”,
modified 33400 baudrate to 38400.
Updated Figure 37-22 “Parity Error” with corrected stop bit value.
TC:
In Section 38.1 “Description”, corrected reference to TIOA1 with TIOB1.
In Section 38.7.3 “TC Channel Mode Register: Waveform Mode”, added note for ENETRG description.
HSMCI:
In Figure 39-8 “Read Functional Flow Diagram”, Figure 39-9 “Write Functional Flow Diagram” and Figure 39-10 “Multiple
Write Functional Flow Diagram”, corrected HSMCI_MR to HSMCI_BLKR when referring to Block Length field that is not
available in HSMCI_MR. Removed related Note 2.
In Section 39.14.7 “HSMCI Block Register”, BLKLEN bit description, removed reference on accessiblity in Mode Register.
