11.3 Timing definitions
The timing requirements of the connected external devices can be fulfilled by programming
different timing configurations. Four different read and write timings can be programmed in
the registers R_BRG_TIM0 . . . R_BRG_TIM3.
The timings are defined by writing the number of idle clock cycles for an access to the
bitmaps V_BRG_TIM0_IDLE . . . V_BRG_TIM3_IDLE of the registers R_BRG_TIM0
. . . R_BRG_TIM3.
V_BRG_TIM0_CLK . . . V_BRG_TIM3_CLK of the same registers.
The timing can be configured for each chip select and read / write operation independently
by programming the registers R_BRG_TIM_SEL01 . . . R_BRG_TIM_SEL67.
