Description

BLOCK0 data register 1.

Fields

RD_DIS

The bit be set to disable software read high/low 128-bit of BLK3.
WDT_DELAY_SEL

Selects RTC watchdog timeout threshold, in unit of slow clock cycle. 0: 40000. 1: 80000. 2: 160000. 3:320000.
DIS_PAD_JTAG

Set this bit to disable pad jtag.
DIS_DOWNLOAD_ICACHE

The bit be set to disable icache in download mode.
DIS_DOWNLOAD_MANUAL_ENCRYPT

The bit be set to disable manual encryption.
SPI_BOOT_ENCRYPT_DECRYPT_CNT

These bits be set to enable SPI boot encrypt/decrypt. Odd number of 1: enable. even number of 1: disable.
XTS_KEY_LENGTH_256

The bit be set means XTS_AES use the whole 256-bit efuse data in BLOCK3. Otherwise, XTS_AES use 128-bit eFuse data in BLOCK3.
UART_PRINT_CONTROL

Set this bit to disable usb printing.
FORCE_SEND_RESUME

Set this bit to force ROM code to send a resume command during SPI boot.
DIS_DOWNLOAD_MODE

Set this bit to disable download mode (boot_mode[3:0] = 0, 1, 2, 4, 5, 6, 7).
DIS_DIRECT_BOOT

This bit set means disable direct_boot mode.
ENABLE_SECURITY_DOWNLOAD

Set this bit to enable secure UART download mode.
FLASH_TPUW

Configures flash waiting time after power-up, in unit of ms. If the value is less than 15, the waiting time is the configurable value. Otherwise, the waiting time is twice the configurable value.
SECURE_BOOT_EN

The bit be set to enable secure boot.
RPT4_RESERVED

Reserved (used for four backups method).
