3.3.Startup Item Configuration
3.3.1. Strapping Pins
The chip allows for configuring the following boot parameters through
strapping pins and eFuse bits at power-up or a hardware reset, without
microcontroller interaction.
Chip Boot Mode
– Strapping pin: GPIO26, GPIO27 and GPIO28
ROM Message Printing
– Strapping pin: GPIO27
– eFuse parameter:
EFUSE_UART_PRINT_CONTROL and EFUSE_DIS_USB_SERIAL_JTAG_ROM_PRINT
JTAG signal source
– Strapping pin: GPIO7
– eFuse parameter:
EFUSE_DIS_PAD_JTAG, EFUSE_DIS_USB_JTAG, and EFUSE_JTAG_SEL_ENABLE
Crystal frequency selection
– Strapping pin: MTMS(effective only in Joint Download Boot mode)
– eFuse parameter:EFUSE_XTAL_48M_SEL and EFUSE_XTAL_48M_SEL_MODE
www.wireless-tag.com

WIRELESS-TAG
WT0132C5-S5 Series Datasheet
The default values of all the above eFuse parameters are 0, which means
that they are not burnt. Given that eFuse is one-time programmable, once
programmed to 1, it can never be reverted to 0.
The default values of the strapping pins, namely the logic levels, are
determined by pins’internal weak pull-up/pull-down resistors at reset if the pins
are not connected to any circuit, or connected to an external high-impedance
circuit.

To change the bit values, the strapping pins should be connected to external
pull-down/pull-up resistors.
All strapping pins have latches. At system reset, the latches sample the bit
values of their respective strapping pins and store them until the chip is powered
down or shut down. The states of latches cannot be changed in any other way. It
makes the strapping pin values available during the entire chip operation, and the
pins are freed up to be used as regular IO pins after reset.
The timing of signals connected to the strapping pins should adhere to the
setup time and hold time specifications in Table and Figure 8.

Joint Download Boot mode 1 supports the following download methods:
UART Download Boot
SDIO Download Boot
In SPI Boot mode, the ROM bootloader loads and executes the program from
SPI flash to boot thesystem.
In Joint Download Boot 0 mode, users can download binary files into flash
using UART0 or USB interfaces. It is also possible to download binary files into
SRAM and execute it from SRAM.
In Joint Download Boot 1 mode, users can download binary files into flash
using UART0 or SDIO interfaces. It is also possible to download binary files into
SRAM and execute it from SRAM.
3.3.3. ROM Messages Printing Control
During the boot process, the messages by the ROM code can be printed to:
(Default) UART0 and USB Serial/JTAG controller

3.3.4. JTAG Signal Source Control
The strapping pin GPIO7 can be used to control the source of JTAG signals
during the early boot process. This pin does not have any internal pull resistors
and the strapping value must be controlled by the external circuit that cannot be in
a high impedance state.
GPIO7 is used in combination with
EFUSE_DIS_PAD_JTAG,EFUSE_DIS_USB_JTAG, and EFUSE_JTAG_SEL_ENABLE.

disabled, then JTAG is disabled.
3.3.5. Crystal Frequency Selection
ESP32-C5 supports crystal frequencies of 40 MHz and 48 MHz. Boot modes
together with MTMS, EFUSE_XTAL_48M_SEL, and
EFUSE_XTAL_48M_SEL_MODE collectively control the crystal frequency.
