the 12C bus.
 Deleted the UART level shifting circuit.
 Updated the power supply range of VRTC_GPS.
 Updated the anode power supply range of LED_K.
 Changed the PWRKEY_N startup time to be greater
than 1.8s and less than 3s.
 Updated the description and function definitions of
PSM_WAKEUP.

 Updated the USB pin name in Figure 4-1 (that is, "HS"
is removed).
 Updated the recommended circuit of a USIM card to
explain the handling method of the USIM_DET pin
when a user uses hot plug or does not use hot plug.
 Deleted the description of "adaptive" because an SD
card does not support adaptive 1.8 V and 3.0 V
(configured based on the software version).
 Updated the dimensions figure and added the "PIN1"
identifier.
 Changed the maximum drive current of the RGB LED
to 50 mA.

 Updated the variants, frequency bands, and regions
of N58 modules in Table 2-1.
 Updated the block diagram in Figure 2-1.
 Updated the description of the application interfaces
in the table of basic features.
 Updated the power consumption data in sleep mode,
idle mode, and operating mode.
 Added chapter 3 "Reference Standards" to describe
the reference standards of the N58 module design.
 Added the VCC_GNSS_BIAS pin description of the
N58 module with the GNSS function.
 Updated the N58 module startup, shutdown, and
reset flowcharts.
 Added the reference design of the module sleep and
wake-up control circuit.
