9.8 Low power select
the oscillator start-up time in cases where Power-down mode would otherwise be
used. The value of DIVM may be changed by the program at any time without
interrupting code execution.
The P89LPC915/916/917 are designed to run at 18 MHz (CCLK) maximum.
However, if CCLK is 8 MHz or slower, the CLKLP SFR bit (AUXR1.7) can be set to
logic 1 to lower the power consumption further. On any reset, CLKLP is logic 0
allowing highest performance access. This bit can then be set in software if CCLK is
running at 8 MHz or slower.
