USR2 (Register 0x101)
Bit 3—Enable GCLK Detect
Normally set high, this bit enables a circuit that detects encode
rates below about 5 MSPS. When a low encode rate is detected,
an internal oscillator, GCLK, is enabled, ensuring the proper
operation of several circuits. If set low, the detector is disabled.
Bit 2—Run GCLK
This bit enables the GCLK oscillator. For some applications
with encode rates below 10 MSPS, it may be preferable to set
this bit high to supersede the GCLK detector.
Bit 0—Disable SDIO Pull-Down
This bit can be set high to disable the internal 30 kΩ pull-down
on the SDIO pin, which can be used to limit the loading when
many devices are connected to the SPI bus.
