| Bit | Field | Type | Reset | Description |
|---|---|---|---|---|
| 31 | MCU_PLL_CLKSEL_BYPASS_SW_OVRD_PROXY | R/W | 0h | PLL Bypass warm reset software override When set, enables software control of exit from bypass mode on a mcu_reset_z for MCU_PLL0. This bit must not be set until after the corresponding byp_warm_rst bit has been cleared or the PLL will immediately enter bypass mode. Field values (others are reserved): 1'b0 - Disable Software control of exit from bypass mode 1'b1 - Enable Software control of exit from bypass mode Reset Source: sys_por_rst_n |
| 30:24 | RESERVED | NONE | 0h | Reserved |
| 23 | MCU_PLL_CLKSEL_BYP_WARM_RST_PROXY | R/W | 1h | PLL bypass mode after warm reset. This bit is only valid when bypass_sw_ovrd is set to 1'b1 to enable bypass software override. This bit is set (1'b1) when a MCU warm reset occurs and will keep MCU_PLL0 in bypass mode after reset exit until cleared by software. Field values (others are reserved): 1'b0 - EXIT_BYPASS 1'b1 - MAINTAIN_BYPASS Reset Source: mcu_chip1_rst_n |
| 22:9 | RESERVED | NONE | 0h | Reserved |
| 8 | MCU_PLL_CLKSEL_CLKLOSS_SWTCH_EN_PROXY | R/W | 0h | When set, enables automatic switching of MCU_PLL0 clock source to CLK_12M_RC if HFOSC0 clock loss is detected Field values (others are reserved): 1'b0 - Disable clock source switching on clock loss 1'b1 - Enable clock source switching on clock loss Reset Source: mod_por_rst_n |
