Configuration Image
When a configuration is sent to the module, it is checked for consistency before
being applied. If an error is found, the PE bit is asserted and the module locally
retains its previous configuration. Your user application program should monitor
the PE bit.

Where:PE = Programming error (error code in bits 11:0)
FP = Field power (24V DC power lost)
NR = Not ready (configuring field programmable array FPGA)
TF = Test fail flag = 1 (indicating failure during powerup) red indicator on.
Code in bits 2:0 indicate fail code (1 = RAM; 2 = ROM; 3 = EEPROM; 4 = FPGA)
Test flag = 1 with red indicator blinking, upper byte of counter control word in non-zero
– in production test mode.
OS = Output status (current state of output)
C1, C0 = Stored data count
ZF = Zero frequency detected
ZS = Z input status

CR = Counter reset (channel)
LC = Local control (channel) - outputs remain under control when FlexBus is unpowered -
1 = enabled
OE = Output enable (channel) - permitting output to be turned on from FO, compare match
or PWM
- 1 = enabled
FO = Forced output (channel) - 1 = on
PWM = Pulse width modulation (0…9500 decimal)
