Clock Description
MPC5606S Microcontroller Reference Manual, Rev. 7
Freescale Semiconductor 199
These registers control the system clock dividers. The divided clock is the reference for the associated
peripheral set.
8.4.3.1.5 Auxiliary Clock 0 Select Control Register (CGM_AC0_SC)
This register is used to select the current auxiliary clock 0 sources.
Table 8-7. System Clock Divider Configuration Registers (CGM_SC_DC0…2) field descriptions
Field Description
DE0 Divider 0 Enable
0 Disable system clock divider 0.
1 Enable system clock divider 0.
DIV0 Divider 0 Division Value — The resultant peripheral set 1 clock will have a period DIV0 + 1 times that of the system
clock. If the DE0 is set to 0 (Divider 0 is disabled), any write access to the DIV0 field is ignored and the peripheral
set 1 clock remains disabled.
DE1 Divider 1 Enable
0 Disable system clock divider 1.
1 Enable system clock divider 1.
DIV1 Divider 1 Division Value — The resultant peripheral set 2 clock will have a period DIV1 + 1 times that of the system
clock. If the DE1 is set to 0 (Divider 1 is disabled), any write access to the DIV1 field is ignored and the peripheral
set 2 clock remains disabled.
DE2 Divider 2 Enable
0 Disable system clock divider 2.
1 Enable system clock divider 2.
DIV2 Divider 2 Division Value — The resultant peripheral set 3 clock will have a period DIV2 + 1 times that of the system
clock. If the DE2 is set to 0 (Divider 2 is disabled), any write access to the DIV2 field is ignored and the peripheral
set 3 clock remains disabled.
