90 / 242 page  6.3.23.3 SYSTEM MAIN Domain Instances Table 6-70. System Signal Descriptions Signal Name [1] Signal Type [2] Description [3] ALV PIN [4] ALX PIN [4] CLKOUT0 O RMII Clock Output (50 MHz). This pin is used for clock source to the external PHY and must be routed back to the RMII_REF_CLK pin for proper device operation. A19, U13 A18, V13 EXTINTn (2) I External Interrupt C19 EXT_REFCLK1 I External clock input to MAIN Domain, routed to Timer clock muxes as one of the selectable input clock sources for Timer/WWDT modules, or as reference clock to MAIN_PLL2 (PER1 PLL) A19 A18 GPMC0_FCLK_MUX (1) O GPMC functional clock output selected through mux logic R17 OBSCLK0 O Observation clock output for test and debug purposes only D17 A15 PORz_OUT O MAIN Domain POR status output E17 D18 RESETSTATz O MAIN Domain warm reset status output F16 E19 RESET_REQz I MAIN Domain external warm reset request input E18 C17 SYSCLKOUT0 O SYSCLK0 output from MAIN PLL controller (divided by 6) for test and debug purposes only C17 B14 (1) The GPMC0_FCLK_MUX signal is not supported by the AM243x_ALX device package. See AM243x_ALX Package - Unsupported Interfaces and Signals for additional details. (2) The EXTINTn signal is not supported by the AM243x_ALX device package. See AM243x_ALX Package - Unsupported Interfaces and Signals for additional details. MCU Domain Instances Table 6-71. MCU System Signal Descriptions Signal Name [1] Signal Type [2] Description [3] ALV PIN [4] ALX PIN [4] MCU_EXT_REFCLK0 (2) I External system clock input B7 MCU_OBSCLK0 O Observation clock output for test and debug purposes only C6, E10 B3 MCU_PORz I MCU Domain cold reset B21 C20 MCU_RESETSTATz O MCU Domain warm reset status output B13 A6 MCU_RESETz I MCU Domain warm reset B12 A5 MCU_SAFETY_ERRORn IO Error signal output from MCU Domain ESM A20 B20 MCU_SYSCLKOUT0 (1) O MCU Domain system clock output for test and debug purposes only C6 (1) The MCU_SYSCLKOUT0 signal is not supported by the AM243x_ALX device package. See AM243x_ALX Package - Unsupported Interfaces and Signals for additional details. (2) The MCU_EXT_REFCLK0 signal is not supported by the AM243x_ALX device package. See AM243x_ALX Package - Unsupported Interfaces and Signals for additional details. 6.3.23.4 VMON Table 6-72. VMON Signal Descriptions Signal Name [1] Signal Type [2] Description [3] ALV PIN [4] ALX PIN [4] VMON_1P8_MCU A Voltage monitor input for 1.8 V MCU power supply K16 VMON_1P8_SOC A Voltage monitor input for 1.8 V SoC power supply E12 F14 VMON_3P3_MCU A Voltage monitor input for 3.3 V MCU power supply F13 VMON_3P3_SOC PWR Voltage monitor input for 3.3 V SoC power supply F14 E15 VMON_VSYS A Voltage monitor input, fixed 0.45 V (+/-3%) threshold. Use with external precision voltage divider to monitor a higher voltage rail such as the PMIC input supply.
