Bit 7: HSE, High Speed operation Enable.
0: Select CPU running in lower speed mode (FCPUCLK
≤
6MHz) which is slow down internal circuit to
reduce power consumption.
1: Enable CPU full speed operation if FCPUCLK > 6MHz. Before select high frequency clock (> 6MHz)
on CPUCLK, software must set HSE to switch internal circuit for high speed operation.
Bit 5: HSE1, High Speed operation Enable 1. 0: No function.
1: Enable MCU for ultra-high speed operation. (FCPUCLK > 25MHz). It also needs to set HSE when use
HSE1 = 1.
