FlexSPI timings with FlexSPIn_MCR0[RXCLKSRC] = 0x3 (DDR mode) ID Parameter Min Max Unit — QSPIx[A/B]_SCLK Cycle frequency — 200 MHz t1 QSPIx[A/B]_SCLK High or Low Time 2.25 — ns t2 QSPIx[A/B]_SSy_B pulse width 1 — SCLK t3 QSPIx[A/B]_SSy_B Lead Time 1 (TCSS+0.5)/2 — SCLK t4 QSPIx[A/B]_SSy_B Lag Time 1 TCSH/2 — SCLK t5 QSPIx[A/B]_DATAy output valid time 0.65 — ns t6 QSPIx[A/B]_DATAy output hold time 0.65 — ns t9 QSPIx[A/B]_DATAy Setup Skew — 0.65 ns t10 QSPIx[A/B]_DATAy Hold Skew — 0.65 ns 1. Timing is controlled from FLSHxCR1 register (x=A1, A2, B1, or B2). 3.10.11 Secure JTAG controller (SJC) 3.10.11.1 Internal pull-up/pull-down configuration The following table describes the default configuration of internal pull-ups and pull- downs of the JTAG interface. External pull-ups and pull-downs are needed when this interface is routed to a connector. Table 73. JTAG default configuration for internal pull-up/pull-down Ball name Internal pull setting1 Typical pull value Unit JTAG_TMS PU 50 KΩ JTAG_TCK PD JTAG_TDI PU TEST_MODE_SELECT PD 1. PU = pull-up; PD = pull-down 3.10.11.2 JTAG timing parameters Figure 47 depicts the SJC test clock input timing. Figure 48 depicts the SJC boundary scan timing. Figure 49 depicts the SJC test access port. Signal parameters are listed in Table 74.
