int seSetClock(CLOCKSELECT ClockSelect, FREQINDEX FreqIndex)
Description:
Parameters:
Return Value:
S1D13506
X25B-G-003-04
Call seSetClock() to set the clock rate of the programmable clock.
ClockSelect The ICD2061A programmable clock chip supports two output clock
signals. ClockSelect chooses which of the two output clocks to adjust.
Valid ClockSelect values are defined by the HAL contents CLKI or
CLKI2
FreqIndex FreqIndex is an enumerated constant and determines what the output
frequency should be.
Valid values for FreqIndex are:
FREQ_6000
FREQ_10000
FREQ_14318
FREQ_17734
FREQ_20000
FREQ_24000
FREQ_25000
FREQ_25175
FREQ_28318
FREQ_30000
FREQ_31500
FREQ_32000
FREQ_33000
FREQ_33333
FREQ_34000
FREQ_35000
FREQ_36000
FREQ_40000
FREQ_49500
FREQ_50000
FREQ_56250
FREQ_65000
FREQ_80000
ERR_OK The function completed with no problems.
ERR_FAILED seSetClock failed the cause may be an invalid ClockSelect or an
invalid frequency index
Note
If seSetClock is called with a ClockSelect of CLKI2 and FreqIndex of FREQ_17734
then the HAL will bypass the programmable clock and select the Feature Clock as the
input clock source. This is done with the assumption that the application is setting up for
TV output and the Feature Clock oscillator will provide a more stable clock for use with
TV. (The feature oscillator must be 17.734 MHz)
