3.12 MISCELLANEOUS CONTROL REGISTER (MISCCR)
In Sleep mode, the data bus(SD[15:0] or RD[15:0] can be set as Hi-Z and Output ‘0’ state. But, because of the
characteristics of IO pad, the data bus pull-up/down resisters have to be turned on or off to reduce the power
consumption. SD[15:0] or RD[15:0] pin pull-up/down resisters can be controlled by MISCCR register.
Pads related USB are controlled by this register for USB host, or for USB device.

NOTES:
1.
User must set first MISCCR[31] = 1’b1 when use the high speed SPI.
2.
We recommend not using this output pad to other device’s pll clock source.
