Programmable bus timing
The length of the bus cycles are user programmable at run time. The number of MCU_CLK
periods in a bus cycle can be specified in the SFR register named BUSCON (see
on page
MCU_CLK periods) after a reset condition. It is important that the post-reset initialization
firmware sets the bus cycle times appropriately to get the most performance, according to
Table 51 on page
and a slower but less power consuming Non-Turbo mode. The bus cycle times must be
programmed in BUSCON to optimize for each mode as shown in
Section 28.5: PSD module detailed operation on page 207
88). By default, the BUSCON register is loaded with long bus cycle times (6
