Low-cost, low-power ARM926EJ-S microcontrollers
[4] One HCLK cycle delay added when SYSCREG_MPMC_WAITREAD_DELAYx register bit 5 = 1.
[5] WAITRD must to WAITOEN for there to be any delay between CS
active and BLS active. The maximum delay is limited to (WAITRD *
HCLK).
[6] There is one less HCLK cycle when SYSCREG_MPMC_WAITREAD_DELAYx bit 5 = 1.
[7] The MPMC will ensure a minimum of one HCLK for this parameter.
[8] This formula applies when WAITWR is WAITWEN. One HCLK cycle minimum.
[9] This formula applies when WAITWR is WAITWEN.
[10] This formula applies when WAITWR is WAITWEN. Data valid minimum One HCLK cycle before WE
goes active.
[11] This formula applies when WAITWR is WAITWEN. Three HCLK cycles minimum.
[12] Refer to the LPC3130/3131 user manual for the programming of WAITRD and HCLK.
[13] Refer to the LPC3130/3131 user manual for the programming of WAITWEN and HCLK.
[14] Refer to the LPC3130/3131 user manual for the programming of WAITWR and HCLK.
