[. . . ] The internal device reset is generated by the AND of POWERGOOD and the RESET pin. 1 = DSP_LDO is disabled and the DSP_LDOO pin is in high-impedance (Hi-Z). The internal voltage monitoring on the DSP_LDOO is bypassed and the internal POWERGOOD signal is immediately set high. If an external power supply is used to provide power to CVDD, then DSP_LDO_EN should be tied to LDOI, DSP_LDOO should be left unconnected, and the RESET pin must be asserted appropriately for device initialization after powerup. Note: to pullup this pin, connect it to the same supply as LDOI pins. CLK_SEL C7 ­ Clock input select. 0 = 32-KHz on-chip oscillator drives the RTC timer and the DSP clock generator. 1 = CLKIN drives the DSP clock generator and the 32-KHz on-chip oscillator drives only the RTC timer. This pin is not allowed to change during device operation; it must be tied to DVDDIO or GND at the board. For proper device operation, external pullup/pulldown resistors may be required on these device configuration pins. For discussion on situations where external pullup/pulldown resistors are required, see Section 4. 8. 1, Pullup/Pulldown Resistors. This device also has RESERVED pins that need to be configured correctly for proper device operation (statically tied high, tied low, or left unconnected at all times). For more details on these pins, see Table 3-18, Reserved and No Connects Terminal Functions. 50 Device Configuration Submit Documentation Feedback Product Folder Link(s): TMS320C5514 Copyright © 2010, Texas Instruments Incorporated TMS320C5514 www. ti. com SPRS646B ­ AUGUST 2010 ­ REVISED AUGUST 2010 4. 6 Configurations After Reset The following sections provide details on configuring the device after reset. For more details on multiplexed pin function control, see Section 4. 7, Multiplexed Pin Configurations. 4. 6. 1 External Bus Selection Register (EBSR) The External Bus Selection Register (EBSR) determines the mapping of the I2S2, I2S3, UART, SPI, and GPIO signals to 21 signals of the external parallel port pins. It also determines the mapping of the I2S or MMC/SD ports to serial port 1 pins and serial port 2 pins. Once the bit fields of this register are changed, the routing of the signals takes place on the next CPU clock cycle. Additionally, the EBSR controls the function of the upper bits of the EMIF address bus. Pins EM_A[20:15] can be individually configured as GPIO pins through the Axx_MODE bits. Before modifying the values of the external bus selection register, you must clock gate all affected peripherals through the Peripheral Clock Gating Control Register. After the external bus selection register has been modified, you must reset the peripherals before using them through the Peripheral Software Reset Counter Register. After the boot process is complete, the external bus selection register must be modified only once, during device configuration. Continuously switching the EBSR configuration is not supported. 15 Reserved 14 PPMODE 12 R/W-000 11 R/W-00 10 SP1MODE 9 SP0MODE 8 R/W-00 R-0 7 Reserved 6 Reserved 5 A20_MODE 4 A19_MODE 3 A18_MODE 2 A17_MODE 1 A16_MODE 0 A15_MODE R-0 R-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 LEGEND: R/W = Read/Write; R = Read only; -n = value after reset Figure 4-4.
