Angel Monitor
Table 3-1 shows the relationship between the clock rate on the board and the serial
baud rate.
Table 3-1. Clock Rate vs. Serial Baud Rate
Note that if the debugger is started through ICE while the SRAM downloader is on, then
both serial channels are enabled.
The Angel monitor is located in the Flash from 0x01002000 up to 0x0100FFFF. It is
started by the boot if neither TIOB1 nor FIQ are pressed at reset.
When Angel starts, it recopies itself into the SRAM in order to run faster. The SRAM
used by Angel is from 0x02020000 to 0x02040000, i.e., the highest half of the SRAM.
The Angel on the AT91EB40 can be upgraded regardless of the version programmed
on it.
Note that if the debugger is started through ICE while the Angel monitor is on, the
Advanced Interrupt Controller (AIC) and the USART channel are enabled.
