{ 59 ns : XSLOW = âHâ
T1=
238 ns : XSLOW = âLâ
Note that XSLOW is bit 7 of DRVIF register.
When XSLOW = âHâ , make sure that the CXD1196AR is connected to an SRAM with an access time of
less than 120 ns.
When XSLOW = âLâ , make sure that the CXD1196AR is connected to an SRAM with an access time of less
than 320 ns.
