This device is warranted under the above listed condition. No warranty made with other
combination or treatments.
Semiconductor devices fail with a known probability. Customer must use safety design ( such as redundant
design, fire proof design, over current prevention design, and malfunction prevention design) so that failures will
not cause accidents, injury or death.
*1: :I=Input pin, O=Output pin , O(T)= Output Tri-state pin, IO=Bi-directional pin, Analog O=Analog output, Analog=Analog
pin for DAC
*2:"<=" mark means treat a pin same as default
*3:Recommend to be same length MCLKI to A, MCLKO to A, SDRAM CLK to A and take care the AC spec of graphics memory
interface.
*4:All of analog pins are possible to connect to GND when NOT use DAC. But if connect to GND, all of analog pins(includes
AVD) have to connect GND.
*5:The internal clock means "others clock"(memory clock, rendering clock,etc) which is set by COT bit of CCF register.
*6: In case of CKM=L, BCLKI is used the both internal clock geometry and others module.
