5.4 Reduced Frequency Mode
The TMPR3901F processor clock frequency can be controlled with the Config register RF field. A slower
processor clock frequency enables lower power dissipation by the TMPR3901F.
The relationship between the RF field and processor clock is follows.
RF[1:0] processor clock/master clock
00 1/1
01 1/2
10 1/4
11 1/8
Note :The R3900 Processor Clock is limited to a minimum operation frequency 5 MHz. Please keep this in
mind when using reduced frequency mode.
