U-Bus to IMB3 Bus Interface (UIMB)
12.2
12.3
The clock module within the UIMB interface generates the IMB3 clock. The IMB3 clock is the main
timing reference used within the IMB3 modules.
The IMB3 clock is generated based on the STOP and HSPEED bits in the UIMB module configuration
register (UMCR). If the STOP = 1, the IMB3 clock is not generated. If the STOP = 0 and the HSPEED =
0, the IMB3 clock is generated as the inversion of the internal system clock. This is the same frequency as
the CLKOUT if SCCR[EBDF] = 0b00 – full speed external bus. (See
then the IMB3 clock is one-half of the internal system frequency. (See
