1. Although this device has a maximum of 231interrupts, the logic requires that the total number of interrupts be divisible by four.
8
Therefore, the total number of interrupts specified for this device is 232.

Simultaneous accesses from different masters to different slaves (there is no clock penalty when a
parked master accesses a slave)
32 channels support independent 8-, 16-, 32-bit single value or block transfers
Supports variable sized queues and circular queues
Source and destination address registers are independently configured to post-increment or remain
constant
Each transfer is initiated by a peripheral, CPU, or eDMA channel request
Each eDMA channel can optionally send an interrupt request to the CPU on completion of a single
value or block transfer
231 total interrupt vectors
— 208 peripheral interrupt requests
— 8 software settable sources
— 16 reserved
Unique 9-bit vector per interrupt source
16 priority levels with fixed hardware arbitration within priority levels for each interrupt source
Priority elevation for shared resources
Input clock frequency:
— 8 to 20 MHz
Current controlled oscillator (ICO) range from 48 MHz to maximum device frequency
Reduced frequency divider (RFD) for reduced frequency operation without re-lock
Four selectable modes of operation
Programmable frequency modulation
Lock detect circuitry continuously monitors lock status
Loss of clock (LOC) detection for reference and feedback clocks
Self-clocked mode (SCM) operation
On-chip loop filter (reduces number of external components required)
Engineering clock output configurable to divide-by-2 to divide-by-510 of the system clock
frequency or the crystal/external clock input
Enhanced Direct Memory Access (eDMA) Controller
Interrupt Controller (INTC)
Frequency Modulated Phase-locked Loop (FMPLL)
