Enhanced Local Bus Controller
13.4.3.3
If BRn[MSEL] selects the FCM, the attributes for the memory cycle are taken from ORn. These attributes
include the CSCT, CST, CHT, RST, SCY, TRLX, and EHTR fields.
13.4.3.3.1
The timing of LCSn assertion in FCM mode is illustrated by the timing diagram in
asserted immediately following LALE negation, and remains asserted until the last instruction in FIR has
completed. The delay, t
instruction is controlled by ORn[CSCT] and ORn[TRLX], as shown in
be set in accordance with the NAND Flash EEPROM chip-select to WE set-up time specification.
13.4.3.3.2
The FCM command (CM0–CM3, CW0, CW1), address (CA, PA, UA), and data write (WB, WS)
instructions all share the same basic timing attributes. Assertion of LFWE initiates transfer via LAD[0:7],
and the options in ORn for FCM mode establish the set-up, hold, and wait state timings with respect to
LFWE, as shown in
