Byte Access Type in Page Mode
The NRD and NCS signals are held low during all read transfers, whatever the programmed val-
ues of the setup and hold timings in the User Interface may be. Moreover, the NRD and NCS
timings are identical. The pulse length of the first access to the page is defined with the
NCS_RD_PULSE field of the PULSE register. The pulse length of subsequent accesses within
the page are defined using the NRD_PULSE parameter.
In page mode, the programming of the read timings is described in
Table 27-6.
The SMC does not check the coherency of timings. It will always apply the NCS_RD_PULSE
timings as page access timing (t

The Byte Access Type configuration remains active in page mode. For 16-bit or 32-bit page
mode devices that require byte selection signals, configure the BAT field of the REGISTER to 0
(byte select access type).
