TABLE 4-2 ADC Channels
The Host microprocessor can monitor up to 7 interrupts of which only 4 are used. The following
table shows the descriptions of the interrupts monitored.
TABLE 4-3 System Interrupts
Upon the release of MAIN_HW_RESETn, the Host microprocessor starts addressing code space
data from the programmed flash part (U5010) starting with all address lines low as the first ad-
dress. The memory map of the Host microprocessor is depicted in the following table.
