S1D13706 Programming Notes and Examples
X31B-G-003-03 Issue Date: 01/02/23
int seSetClock(CLOCKSELECT ClockSelect, FREQINDEX FreqIndex)
Description:
Call seSetClock() to set the clock rate of the programmable clock.
Parameters:
ClockSelect The ICD2061A programmable clock chip supports two output clock
signals. ClockSelect chooses which of the two output clocks to adjust.
Valid ClockSelect values for CLKI or CLKI2 (defined in HAL.H).
FreqIndex FreqIndex is an enumerated constant and determines what the output
frequency should be.
Valid values for FreqIndex are:
FREQ_6000 6.000 MHz
FREQ_10000 10.000 MHz
FREQ_14318 14.318 MHz
FREQ_17734 17.734 MHz
FREQ_20000 20.000 MHz
FREQ_24000 24.000 MHz
FREQ_25000 25.000 MHz
FREQ_25175 25.175 MHz
FREQ_28318 28.318 MHz
FREQ_30000 30.000 MHz
FREQ_31500 31.500 MHz
FREQ_32000 32.000 MHz
FREQ_33000 33.000 MHz
FREQ_33333 33.333 MHz
FREQ_34000 34.000 MHz
FREQ_35000 35.000 MHz
FREQ_36000 36.000 MHz
FREQ_40000 40.000 MHz
FREQ_49500 49.500 MHz
FREQ_50000 50.000 MHz
FREQ_56250 56.250 MHz
FREQ_65000 65.000 MHz
FREQ_80000 80.000 MHz
FREQ_100000 100.000 MHz
Return Value:
ERR_OK The function completed with no problems.
ERR_FAILED seSetClock failed because of an invalid ClockSelect or an invalid
frequency index.
10.2.3 Surface Support
The S1D13706 HAL library depends heavily on the concept of surfaces. Through surfaces
the HAL tracks memory requirements of the main window and sub-window.
Surfaces allow the HAL to permit or fail function calls which change the geometry of the
S1D13706 display memory. Most HAL functions either allocate surface memory or manip-
ulate a surface that has been allocated.
