45.4.1 ISI Control 1 Register
Name: ISI_CR1
Address: 0xFFFC4000
Access: Read/Write
• ISI_RST: Image sensor interface reset
Write-only. Refer to bit SOFTRST in Section 45.4.3 “ISI Status Register” on page 1009 for soft reset status.
0: No action
1: Resets the image sensor interface.
• ISI_DIS: Image sensor disable:
0: Enable the image sensor interface.
1: Finish capturing the current frame and then shut down the module.
• HSYNC_POL: Horizontal synchronization polarity
0: HSYNC active high
1: HSYNC active low
• VSYNC_POL: Vertical synchronization polarity
0: VSYNC active high
1: VSYNC active low
• PIXCLK_POL: Pixel clock polarity
0: Data is sampled on rising edge of pixel clock
1: Data is sampled on falling edge of pixel clock
• EMB_SYNC: Embedded synchronization
0: Synchronization by HSYNC, VSYNC
1: Synchronization by embedded synchronization sequence SAV/EAV
• CRC_SYNC: Embedded synchronization
0: No CRC correction is performed on embedded synchronization
1: CRC correction is performed. if the correction is not possible, the current frame is discarded and the CRC_ERR is set in
the status register.
