MAX6954
4-Wire Interfaced, 2.7V to 5.5V LED Display
Driver with I/O Expander and Key Scan

_______________________________________________________________________________________
Reading Device Registers
Any register data within the MAX6954 may be read by
sending a logic high to bit D15. The sequence is:
1) Take CLK low.
2) Take
CS low. This enables the internal 16-bit shift
register.
3) Clock 16 bits of data into DIN, D15 first to D0 last.
D15 is high, indicating a read command and bits
D14 through D8 contain the address of the register
