7.6.7Reset Controller Register

The reset type status (RSTYPE) register (029A 00E4) is the only register for the reset controller. This register falls in the same memory range as the PLL1 controller registers [029A 0000 - 029A 01FF] (see Table 7-18).

7.6.7.1 Reset Type Status Register Description

The rest type status (RSTYPE) register latches the cause of the last reset. If multiple reset sources occur simultaneously, this register latches the highest priority reset source. The reset type status register is shown in Figure 7-7and described in Table 7-13.
