Serial Control Interface
Internal registers may be written by using the 3-wire μP interface pins (CSN, CCLK and CDTIO). The data on this
interface consists of Read/Write, Register address (MSB first, 7bits) and Control data (MSB first, 8bits). Each bit is
clocked in on the rising edge (“
”) of CCLK. It is available for writing data on the rising edge of CSN. When reading
operation, CDTIO pin has become an output mode at the falling edge of 8
th
CCLIC and outputs D7-D0. The output
finishes on the rising edge of CSN. The CDTIO is placed in a Hi-Z state except outputting data at read operation mode.
Clock speed of CCLK is 5MHz (max). The value of internal registers are initialized by PDN pin = “L”.
Note 38. It is available for reading the address 00H~11H. When reading the address 12H
7FH, the register values are
invalid.
