Pulse-Width Modulator (S12PWM8B8CV1)
S12XS Family Reference Manual, Rev. 1.13
366 Freescale Semiconductor
13.1.2 Modes of Operation
There is a software programmable option for low power consumption in wait mode that disables the input
clock to the prescaler.
In freeze mode there is a software programmable option to disable the input clock to the prescaler. This is
useful for emulation.
