Repeat area
1. R0[7:0] address input is latched when AH(R10), AL(R11) is rising.
2. R0[7:0] Data out (DOUT) is valid during R17 is `Low`.
3. Writing time (R16 is `Low`) is 200us, and verify data.
Maximum repeat count is 20.
4. If cell can not be programmed within maximum repeat count, judge as IC is fail.
AH : High Byte Address Input
AL : Low Byte Address Input
DIN : Data Input
DOUT : Data Output
