Control Register R/W Timing
The data on the 4 wires serial interface consists of op-code(3bit), address(LSB-first, 5bit) and control data
(LSB-first, 8bit). The transmitting data is output to each bit by "
" of CCLK, the receiving data is latched by "
"
of CCLK. Writing data becomes effective by "
" of CS. Reading data becomes Hi-Z(floating) by "
" of CS.
CS should be held to "H" at no access. In case of connecting between CDTI and CDTO, the I/F can be also
controlled by 3-wires.
CCLK always needs 16 edges of "
" during
CS
="L". Reading/Writing of the address except 00H
0DH are
inhibited.
Reading/Writing of the control registers by except op0=op1="1" are invalid.
op0- op2: Op- code (111:WRITE, 110:READ)
