PLL Controller Registers

5.4.1 Peripheral ID Register (PID)

The peripheral ID register (PID) is shown in Figure 5-3and described in Table 5-5.

5.4.2 Reset Type Status Register (RSTYPE)

The reset type status register (RSTYPE) is shown in Figure 5-4and described in Table 5-6. It latches cause of the last reset. Although the reset value of all bits is 0 after coming out of reset, one bit is set to 1 to indicate the cause of the reset.

Bit	Field	Value	Description
31-3	Reserved	0	Reserved
2	MRST	0-1	Maximum reset. If 1, maximum reset was the reset to occur that is of highest priority.
1	XWRST	0-1	External warm reset. If 1, warm reset (RESET) was the last reset to occur that is of highest priority.
0	POR	0-1	Power on reset. If 1, power on reset (POR) was the last reset to occur that is of highest priority.
