Hi
I need to have 2 I2S outputs to slave devices but need to bump the pin allocations to the opposite side of the device on a ZCZ package. A compromise to keep the USB / MMC routing better
First I2S assignment
I2S_BCLK / MCASP0_ACLKX moved to K18
I2S_FCLK / MCASP0_FSX moved to L18
I2S_DATA / MCASP0_AXR0 moved to L17
I would also like to dispense with the oscillator on the DAC for MCLK to save on an oscillator cost, this should be OK to take from K15 ??? (McASP0-AHCLKX)
I2S_BCLK / MCASP1_ACLKX moved to J17
I2S_FCLK / MCASP1_FSX moved to J18
I2S_DATA / MCASP1_AXR0 moved to J16
I would also like to dispense with the oscillator on the DAC for MCLK to save on an oscillator cost, this should be OK to take from H18 ??? (McASP0-AHCLKX)
Other than configuring these in the PinMux utility (which looks OK) any issues I should consider ?
Both I2S interfaces are slaves and i2C controlled
There is a 24 Bit LCD interface which eats up some pins but there is no Ethernet used at all. Basically 3 x MMC interfaces (with WiLink on MMC1 Interface at 1V8 to save the shifters) and MMC0/2 on 3V3
It would have been nice to get the DACS on a 1V8 interface but seems not possible.
