7.9.2 Initialization Sequence at Power ON
Figure 16. AS8510 Device Initialization Sequence at Power ON
Device initialization starts if the DVDD and AVDD supplies are switched ON and DVDD > VPORHID. The duration period of Initialization is 500
μsec
and during this period, INT pin toggles at the rate of internal low power oscillator. Toggling on INT during the period of initialization should be
ignored in the system. Device configuration and activation should be carried out only after the initialization period.
On ADC start, device enters into analog stabilization state and takes 1.5msec for oscillator and Reference to settle. After this 1.5msec period, the
first interrupt will occur after a time period of TADC.
TDATA_STATUS_RD is the time period during which the micro-controller should complete reading of data and status from the device. If reading is
carried out beyond this time period, then, ADC performance will degrade for next sample generation. Status register gets cleared automatically
only when micro-controller reads this register. Data in the channel registers is changed after TDATA_VALID duration. Ensure that data channel
registers and status registers are not read during the TDATA_INVALID duration.
Example:
Configuration registers are set as follows:
CLK_REG = 8’b0010_0000
DEC_REG_R1_I = 0100_0101
DEC_REG_R2_I = 1100_0101
FIR_CTL_REG_I = 0000_0100
ADC is configured to a data rate of 1KHz, CHOP_CLK to 2KHz, and Modulator clock to 1MHz, Decimation ratio of CIC1 = 64, and Decimation
ratio of CIC2 = 4. With these settings the various time periods as shown in the Figure 16 are as follows:
TDATA_STATUS_RD = 100
μsec
(TDATA_STATUS_RD = (1/mod_clk) * R1 * [((mod_clk/(2*chop_clk))*(1/R1)) - 2.5)
TDATA_INVALID = 8
μsec
TADC = 1msec
TDATA_VALID = TADC - TDATA_INVALID = 1msec - 8
μsec
CHOP_CLK and POR_N are internal signals of the device.
