4.2.1
A reset is the highest-priority exception. There are two types of reset: power-on reset and manual
reset. As table 4.4 shows, a power-on reset initializes the internal state of the CPU and all registers
of the on-chip supporting modules. A manual reset initializes the internal state of the CPU and all
registers of the on-chip supporting modules except the bus state controller (BSC), pin function
controller (PFC), and I/O ports (I/O).
