4.9.5.2
All WEIM output control signals may be asserted and deasserted by internal clocks related to the BCLK
rising edge or falling edge according to the corresponding assertion or negation control fields. The address
always begins related to BCLK falling edge but may be ended both on rising and falling edge in muxed
mode according to control register configuration. Output data begins related to BCLK rising edge except
in muxed mode where both rising and falling edge may be used according to control register configuration.

Wireless External Interface Module (WEIM)
High is defined as 80% of signal value and low is defined as 20% of signal
value.
Timing for HCLK is 133 MHz and internal NFC clock (flash clock) is
approximately 33 MHz (30 ns). All timings are listed according to this NFC
clock frequency (multiples of NFC clock phases), except NF16 and NF17,
which are not NFC clock related.
