3.5.10 FeRAMs PID constant read/write completion flag (buffer memory address 31:
Un\G31)
(1) This flag indicates a normal completion or failure of the following functions.
• FeRAMs PID constant read command (buffer memory address: 62, 94)
• Automatic backup setting after auto tuning of PID constants (buffer memory
address: 63, 95)
The following table indicates the definitions of the bits.
Bit number Flag definition Bit number Flag definition
b0 Channel 1 read completion b8 Channel 1 read failure
b1 Channel 2 read completion b9 Channel 2 read failure
b2 Unused b10 Channel 3 read failure
b3 Unused b11 Channel 4 read failure
b4 Channel 1 write completion b12 Channel 1 write failure
b5 Channel 2 write completion b13 Channel 2 write failure
b6 Unused b14 Channel 3 write failure
b7 Unused b15 Channel 4 write failure
(2) The following chart shows the ON/OFF timings of this flag relative to the
FeRAMs PID constant read command (buffer memory address: 62, 94). (For
channel 1)
