System Reset and Booting
This conservative behavior lets the host send data with high data rates
without knowing the structure of the boot stream. The most critical speed
path during the entire boot procedure is the time during when the kernel
received the 10th bytes and must still evaluate the block header before it
can drive
HWAIT
. For the highest data rate, the host is encouraged to per-
form these steps:
1. Send the first 10 bytes.
2. Wait until
HWAIT
goes active.
3. For every further byte, wait until
HWAIT
is inactive and then send
the next byte.
Final Initialization
After the successful download of the application into the bootable mem-
ory, and before jumping to the
EVT1
vector address, the boot kernel does
some housekeeping work. Most of the used registers are changed back to
their default state, but some register values may differ for the individual
boot modes. These registers are reset to 0x0:
• SPI_CTL
• UART0_GCTL
• UART0_IER
• TWI_CONTROL
• MDMA_S0_CONFIG
• MDMA_D0_CONFIG
• MDMA_S1_CONFIG
• MDMA_D1_CONFIG
• DMA7_CONFIG
