213 / 923 page  175 • Bits 3–0—CS Assert Extension Specification (SW3, SW2, SW1, SW0): The CS assert cycle extension specification is for making insertions to prevent extension of the RD signal or WRx signal assert period beyond the length of the CSn signal assert period. Extended cycles insert one cycle before and after each bus cycle, which simplifies interfaces with external devices and also has the effect of extending write data hold time. Refer to section 10.3.3, CS Assert Period Extension, for details. SW3 specifies the CS assert extension for CS3 space access; SW2 specifies the CS assert extension for CS2 space access; SW1 specifies the CS assert extension for CS1 space access and SW0 specifies the CS assert extension for CS0 space access. Bit 3 (SW3) Description 0 No CS3 space CS assert extension 1 CS3 space CS assert extension (initial value) Bit 2 (SW2) Description 0 No CS2 space CS assert extension 1 CS2 space CS assert extension (initial value) Bit 1 (SW1) Description 0 No CS1 space CS assert extension 1 CS1 space CS assert extension (initial value) Bit 0 (SW0) Description 0 No CS0 space CS assert extension 1 CS0 space CS assert extension (initial value) 10.2.3 Wait Control Register 1 (WCR1) WCR1 is a 16-bit read/write register that specifies the number of wait cycles (0–15) for each CS space. WCR1 is initialized by power-on resets to H'FFFF, but is not initialized by manual resets or software standbys. |
