MPC5604B/C Microcontroller Reference Manual, Rev. 8
904 Freescale Semiconductor
Clock Description Replaced the “MPC5604B system clock generation” figure with the version present in Rev.
5 of the MPC5604B reference manual.
Fast external crystal oscillator (FXOSC) digital interface section: Changed the sentence
from “The FXOSC digital interface controls the 4–40 MHz fast external crystal oscillator
(FXOSC).” to “The FXOSC digital interface controls the operation of the 4–40 MHz fast
external crystal oscillator (FXOSC).”
Truth table of crystal oscillator table: Replaced "ME_GS.S_XOSC" with
“ME_xxx_MC[FXOSCON]", replaced “FXOSC_CTL.OSCBYP” with
“FXOSC_CTL[OSCBYP]”
Slow external crystal oscillator (SXOSC) digital interface section: Changed the sentence
from “The SXOSC digital interface controls the 32 KHz slow external crystal oscillator
(SXOSC).” to “The SXOSC digital interface controls the operation of the 32 KHz slow
external crystal oscillator (SXOSC).”
SXOSC truth table: Replaced "S_OSC” with “OSCON"
Renamed the figure title
from “RC Oscillator Control Register (RC_CTL)”
to “FIRC Oscillator Control Register (FIRC_CTL)”
Renamed the table title
from “RC Oscillator Control Register (RC_CTL) field descriptions”
to “FIRC Oscillator Control Register (FIRC_CTL) field descriptions”
In the FXOSC_CTL figure, added footnotes to clarify the access to the OSCBYP and
I_OSC fields.
Deleted the “CMU register map” section.
Added notes for clarifying field access to the following registers
• FXOSC_CTL
• SXOSC_CTL
•CMU_CSR
Revised the SXOSC_CTL section.
In the SIRC “Functional description” section, revised the information of SIRC output
frequency trimming.
In the FIRC “Functional description” section, revised the information of FIRC output
frequency trimming.
In the FIRC_CTL section, deleted the FIRCON_STDBY field.
Revised the reset values in the FMPLL CR.
Revised the SIRC_CTL[SIRCTRIM] field description.
Revised the FIRC_CTL[FIRCTRIM] field description.
Changed STANDBY0 to STANDBY.
In the FMPLL features, changed “SSCG” to “frequency modulation”.
In the FMPLL functional description, added the “FMPLL lookup table” table.
In the CMU introduction, changed “towards the mode” to “towards the MC_ME”.
In the CMU introduction, deleted the “CMU block diagram” figure.
In the CMU Introduction section, changed “clock management unit” to MC_CGM.
Mode Entry Module Changed “WARNING” to “CAUTION”.
Changed HALT0 to HALT.
Changed STOP0 to STOP.
Changed STANDBY0 to STANDBY.
Added the “Peripheral control registers by peripheral” table.
In the ME_<mode>_MC[DFLAON] field description, added a note about configuring reset
sources as long resets.
