start of the cycle:
D When FS is not used ( FS = 1 at the falling edge of CS), the falling edge of CS is the start of the cycle. Input
data is shifted in on the rising edge of SCLK, and output data changes on the falling edge of SCLK. This
is typically used for a SPI microcontroller although it can also be used for a DSP.
D When FS is used ( FS is an active signal from a DSP), the falling edge of FS is the start of the cycle. Input
data is shifted in on the falling edge, and output data changes on the rising edge of SCLK. This is typically
used for a TMS320 DSP.
first 4-MSBs: the command register (CMR)
The TLV2544/TLV2548 have a 4-bit command set (see Table 1) plus a 12-bit configuration data field. Most of
the commands require only the first 4 MSBs, i.e. without the 12-bit data field.
NOTE:
The device requires a write CFR (configuration register) with 000h data (write A000h to the serial
input) at power up to initialize host select mode.
The valid commands are listed in Table 1.
