commands, Table 18: List of registers - Space B, Table 24: Target

operation modes, Table 20: IO configuration register 2, Table 21:

Operation control register, Table 40: Receiver configuration register 1,

Table 68: Collision display register, Table 90: Regulator voltage control

Table 118: Absolute maximum ratings, Table 119: Operating conditions,

Table 120: Characteristics of CMOS I/Os, Table 121: ST25R3916/7

electrical characteristics (VDD = 3.3 V), Table 122: ST25R3916/7

electrical characteristics (VDD = 5.5 V), Table 123: ST25R3916/7

electrical characteristics (VDD = 2.4 V), Table 124: SPI characteristics (5

MHz), Table 125: SPI characteristics (5 MHz < 1 / TSCLK < 10 MHz),

Table 129: DC characteristics, Table 130: 100 kHz AC characteristics,

Table 132: 1 MHz AC characteristics, Table 133: 3.4 MHz AC

characteristics and Table 135: WLCSP36 mechanical data.

and its subsections, Section 4.3.1: Interrupt interface, Section 4.3.4: I2C

interface, Section 4.4.17: Test access and Section 6.2: WLCSP36

package information.

Added Figure 35: I2C AC measurements.

Removed former Table 114: Characteristics of CMOS I/Os (VDD = 2.4 to

5.5 V, characterized only), Table 116: SPI characteristics (VDD = 2.4 to

5.5 V, VDD_IO = 3.3 V), Table 127: 1 MHz AC characteristics (VDD = 2.4

to 5.5 V, VDD_IO = 1.65 V) and Table 129: 3.4 MHz AC characteristics

(VDD = 2.4 to 5.5 V, VDD_IO = 1.65 V).
