K12P64M50SF4 Datasheet, PDF (53/58 Pages) Freescale Semiconductor, Inc – K12 Sub-Family Data Sheet

K12, K21, and K22 devices and are not present on K10 and
K20 devices.
• The TRACE signals on PTE0, PTE1, PTE2, PTE3, and
PTE4 are available only for K11, K12, K21, and K22
devices and are not present on K10 and K20 devices.
• If the VBAT pin is not used, the VBAT pin should be left
floating. Do not connect VBAT pin to VSS.
• The FTM_CLKIN signals on PTB16 and PTB17 are
available only for K11, K12, K21, and K22 devices and is
not present on K10 and K20 devices. For K12D devices
this signal is on ALT7, and for K12F devices, this signal is
on ALT4.
