P89LPC9331/9341/9351/9361
8-bit microcontroller with accelerated two-clock 80C51 core
7.10 CCLK wake-up delay
The P89LPC9331/9341/9351/9361 has an internal wake-up timer that delays the clock
until it stabilizes depending on the clock source used. If the clock source is any of the
three crystal selections (low, medium and high frequencies) the delay is 1024 OSCCLK
cycles plus 60
μsto100 μs. If the clock source is the internal RC oscillator, the delay is
200
μs to 300 μs. If the clock source is watchdog oscillator or external clock, the delay is
32 OSCCLK cycles.
7.11 CCLK modification: DIVM register
The OSCCLK frequency can be divided down up to 510 times by configuring a dividing
register, DIVM, to generate CCLK. This feature makes it possible to temporarily run the
CPU at a lower rate, reducing power consumption. By dividing the clock, the CPU can
retain the ability to respond to events that would not exit Idle mode by executing its normal
program at a lower rate. This can also allow bypassing 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.
7.12 Low power select
The P89LPC9331/9341/9351/9361 is 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.
