Value given for lowest possible CLKIN frequency 18 MHz to ensure proper initialization of reset sequence.
Reset Configuration
Input line sampled by the MSC8103 at the rising
edge of PORESET.
EONCE Event Bit 0
Input line sampled after SC140 core PLL locks.
Holding EE0 high when PORESET is deasserted
puts the SC140 core into Debug mode.
Host Port Enable
Input line sampled at the rising edge of PORESET.
If asserted, the Host port is enabled, the system
data bus is 32-bit wide, and the Host must
program the reset configuration word.
Boot Mode
Input lines sampled at the rising edge of
PORESET, which determine the MSC8103 Boot
mode.
