6.5.6.3
This bit controls the pull-up resistors on the IRQA pin.
6.5.6.4
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
6.5.6.5
This bit controls the pull-up resistors on the TRST (This pin is always tied inactive on the 56F8322), TMS
and TDI pins.
6.5.6.6
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
6.5.7
The CLKO select register can be used to multiplex out any one of the clocks generated inside the clock
generation and SIM modules. The default value is SYS_CLK. All other clocks primarily muxed out are
for test purposes only, and are subject to significant unspecified latencies at high frequencies.
The upper four bits of the GPIOB register can function as GPIO, Quad Decoder #0 signals, or as additional
clock output signals. GPIO has priority and is enabled/disabled via the GPIOB_PER. If GPIOB[7:4] are
programmed to operate as peripheral outputs, then the choice between Quad Decoder #0 and additional
clock outputs is made here in the CLKOSR. The default state is for the peripheral function of GPIOB[7:4]
to be programmed as Quad Decoder #0. This can be changed by altering PHASE0 through INDEX as
shown in
The CLKOUT pin is not bonded out in this device. Instead, it is offered only as a pad for die-level testing.
6.5.7.1
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
