Watchdog (WD) timer and CSI connection
SW1: Watchdog or CSI can be switched by selecting GPIO44,45. Watchdog (WD) and CSI
cannot be used at the same time. When WD is selected, GPIO44 and 45 are for WD
operation. In addition, when SW3: No.1 of protection SW is off, the reset is forcibly disabled.
When CSI is selected, GPIO44 and 45 are used as i2c for CSI.
