Interrupt Controller Registers in Master Mode
MASTER MODE INTERRUPT CONTROLLER REGISTERS
The interrupt controller registers for master mode are shown in Table 7-2. All the registers
can be read and written unless otherwise specified.
Registers can be redefined in slave mode. See Section 7.4 on page 7-28 for detailed
information regarding slave mode register usage. On reset, the microcontroller is in master
mode. Bit 14 of the Peripheral Control Block Relocation register (see Figure 4-1) must be
set to initiate slave mode operation.
