(7-5) Internal flag register and configuration register
There is RAM area inside the camera consisting of flag register (FR) (2 bytes) and configuration register (CR) (2 bytes)
which defines the operational mode of the camera.
It is possible to recognize the current operational status with these register contents and to change multiple operational
modes at a time by rewriting the register contents using serial communication command.
The functions of each flag register and configuration register are described below.
Flag register (FR) and configuration register (CR)
●
The contents of the internal EEPROM (nonvolatile ROM) are retrieved at the time of startup and copied onto FR and CR
which are the double-byte (16-bit) storage area on RAM. The camera decides the current operational mode in accordance
with the contents of FR and CR.
The one each of the contents of FR is saved on each program page (A to F) and that contents is copied onto the flag
register to decide the operational status by auto-loading on start-up or manual loading of program page. In contrast, the
contents of CR is saved on a single storage area on EEPROM and they are read out independently of program page to
decide the operational mode.
Contents of (FR) and (CR )
●
When the OSD menu is turned on, the contents of each register are displayed on the menu in eight figures like
"MF=0000.0000" representing the current status of the registers.
Each numerical value is displayed in hexadecimal system. The first half (upper 2 bytes) represents the set contents of the
configuration register (CR) and the last half (lower 2 bytes) represents the set contents of the flag register (FR).

15 DFER Request for reading out default value at next start-up
(Note) The contents of CR are " H'0008 " by default (Factory default).
[Contents of FR]
Bit Abbrev.
0 ASYE Selection of continuous/asynchronous shutter
1 PWCE Selection of enabled/disabled for pulse width control
2 LEXE Selection of high speed/low speed shutter
3 PSCE- Selection of normal scan/partial scan

7 - (not used)
8 ESP(0)
9 ESP(1)
Externally designated shutter speed position
10 ESP(2)
11 ESP(3)
12 ESPE Validity of externally designated shutter speed
- (not used)

14 AECE Validity of auto Exposure Control
15 AGCE Validity of auto Gain Control
(Note) The contents of FR are all "0" by default (Factory default).
(Example) If "MF=H'0040.0003" is displayed on the menu screen, the camera is in the following state (converting the
numbers to ones in binary system):
H'00=B'00000000, H'40=B'01000000 and H'03=00000011 are substituted to the above numbers.
CR=B'0000000001000000, FR=B'0000000000000011
......... CR(6)=FR(1)=FR(0)=1, All other bits = 0
(Where CR(n) and FR(m) represent the nth bit of CR and mth bit of FR respectively)
Based on 1 or 0 of these bits and the information in the above table, the user can know that the camera is in the
state of "Enabled STRB signal output in the continuous shutter", "ASYNC" and "Enabled pulse width control".
