SIO(RS232) Special Commands
0xF2F10018
Auto-Sync Mode control register
Bit 31 : auto sync enable
Bit 30 : SIO enable mode (0 : Custom mode, 1 : IIDC v1.31)
Bit 27 : auto sync complete (read only. 1: ready, 0: not yet auto-sync)
Read/Write
Custom commands are valid when the Bit30 is to be set “0”(zero).
SIO(RS232) custom commands are non IIDC compliant which is a specific mode for the cameras.
Before using these commands serial communication parameters must be set at Serial_Mode_Reg(F2F22000h)
F2F10018 means that the RS232 command is valid.
