2783 2783 Audioout_ctrl_edge_sync bit is not used (audioin_ctrl_edge_sync is used for ADC and DAC) Description: The EDGE_SYNC bit in AUDIOOUT_CTRL register has no effect on the DAC. Workaround: The EDGE_SYNC bit in AUDIOIN_CTRL register should be used for both DAC and ADC. Chip Errata for the i.MX23, Rev. 2 12 Freescale Semiconductor
2786 JTAG crash when HCLK is less than 24 MHz. Description: The chip can appear to “crash” when using JTAG to debug code and the clocks are changed such that HCLK is set to less than 24 MHz. The “crash” is not actually a chip problem in that the chip does continue to run. But it is no longer possible to halt or stop at a breakpoint via the debugger, so it seems that the chip has died. Workaround: The workaround is to set the debugger JTAG target clock to 700 kHz or lower, depending on how low HCLK is set. The lower HCLK is set, the lower the JTAG target clock must be set. For example, a JTAG target clock setting of 100 kHz is recommended for HCLK at 3 MHz. If HCLK is 12 MHz, 700 kHz is recommended. Where HCLK is from 12 MHz up to 24 MHz, no higher than 700 kHz is recommended. This is only required when using JTAG to debug portions of code where HCLK can be below 24 MHz (stopping at breakpoints, stepping, and so on). For downloading code via JTAG or debugging where HCLK is at or above 24 MHz, the JTAG target clock can be at 1 MHz. Chip Errata for the i.MX23, Rev. 2 Freescale Semiconductor 13 2786
