Byte 1: CPU, 24/48 MHz Active/Inactive Register (1 = enable, 0 = disable)
Notes:
Bit 7 enables/disables Pin 28 (F1) when the output is 24 MHz (SEL1 = 1).
Bits 0 and 1 must always be at the same state. Bits 2 and 3 must always be at the same state.
Byte 2: PCI Active/Inactive Register (1 = enable, 0 = disable)
Notes:
Bit 3 enables/disables Pin 28 (F1) when the output is PCI (SEL1 = 0).
