bypass
Contains fields that control bypass for clocks derived from the Peripheral PLL.
1: The clock is bypassed.
0: The clock is derived from the 5:1 active mux.
| Module Instance | Base Address | Register Address |
|---|---|---|
| i_clk_mgr_perpllgrp | 0xFFD040C0 | 0xFFD040D4 |
Offset: 0x14
Access: RW
Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

bypass Fields
| Bit | Name | Description | Access | Reset |
|---|---|---|---|---|
| 7 | fben | If set, the pll_main_fben_clk will be bypassed to the boot_clk. The pll_main_fben_clk is used to synchronously update the Numerator to the Main PLL. |
RW | 0x1 |
| 6 | rfen | If set, the pll_peri_rfen_clk will be bypassed to the boot_clk. The pll_peri_rfen_clk is used to synchronously update the Denominator to the Peripheral PLL. |
RW | 0x1 |
| 5 | s2fuser1 | If set, the s2f_user1_clk will be bypassed to the boot_clk. |
RW | 0x1 |
| 4 | sdmmc | If set, the sdmmc_clk will be bypassed to the boot_clk. |
RW | 0x1 |
| 3 | gpiodb | If set, the gpio_db_clk will be bypassed to the boot_clk. |
RW | 0x1 |
| 2 | emacptp | If set, the emac_ptp_clk will be bypassed to the boot_clk. |
RW | 0x1 |
| 1 | emacb | If set, the emacb_free_clk will be bypassed to the boot_clk. |
RW | 0x1 |
| 0 | emaca | If set, the emaca_free_clk will be bypassed to the boot_clk. |
RW | 0x1 |
