NOTE
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.
4.3.9.2
Wireless External Interface Module (WEIM)
All WEIM output control signals may be asserted and deasserted by internal clock related to BCLK rising
edge or falling edge according to corresponding assertion/negation control fields. 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. Input data,
ECB and DTACK all captured according to BCLK rising edge time. Figure 27 depicts the timing of the
WEIM module, and Table 33 lists the timing parameters.
