Clock Architecture Description
The CYRF69213 clock selection circuitry allows the selection
of independent clocks for the CPU, USB, Interval Timers, and
Capture Timers.
The CPU clock, CPUCLK, can be sourced from the external
crystal oscillator or the Internal 24-MHz Oscillator. The
selected clock source can optionally be divided by 2
n
where
n
is 0–5,7 (see
Table 34
).
USBCLK, which must be 12 MHz for the USB SIE to function
properly, can be sourced by the Internal 24-MHz Oscillator or
the external crystal oscillator. An optional divide-by-two allows
the use of the 24-MHz source.
The Interval Timer clock (ITMRCLK), can be sourced from the
external crystal oscillator, the Internal 24-MHz Oscillator, the
Internal 32-KHz Low-power Oscillator, or from the timer
capture clock (TCAPCLK). A programmable prescaler of 1, 2,
3, 4 then divides the selected source.
The Timer Capture clock (TCAPCLK) can be sourced from the
external crystal oscillator, Internal 24-MHz Oscillator, or the
Internal 32-KHz Low-power Oscillator.
When it is not being used by the external crystal oscillator, the
CLKOUT pin can be driven from one of many sources. This is
used for test and can also be used in some applications. The
sources that can drive the CLKOUT are:
CLKIN after the optional EFTB filter
Internal 24-MHz Oscillator
Internal 32-KHz Low-power Oscillator
CPUCLK after the programmable divider
