PLL_CTRL Register Field Descriptions Bit Field Type Reset Description 7 RESERVED R/W 0h 6 EN_PLL R/W 0h Selection of external clock and PLL operation: 0 – Forced to internal RC oscillator. PLL disabled. 1 – PLL is enabled in STANDBY and ACTIVE modes. Automatic external clock use when available, interrupt generated if external clock appears or disappears. (Default from OTP memory) 5 EN_FRAC_DIV R/W 0h This bit must be set to '0'. 4-0 EXT_CLK_FREQ R/W 2h Frequency of the external clock (CLKIN): 0x00 – 1 MHz 0x01 – 2 MHz 0x02 – 3 MHz ... 0x16 – 23 MHz 0x17 – 24 MHz 0x18...0x1F – Reserved See electrical specification for input clock frequency tolerance. (Default from OTP memory) Note: To ensure proper operation of PLL, EXT_CLK_FREQ value must not be changed when PLL is enabled. 7.6.1.1.20 PGOOD_CTRL Register (Offset = 13h) [reset = 0h] PGOOD_CTRL is shown in Figure 7-38 and described in Table 7-30.
