INUSE_OFF,

INUSE_ON

Mode bits x. Switches the port resource on (value ) and

off (value ). Before using a port it must be switched on.

COND_NONE, COND_EQ,

COND_NEQ

Mode bits x. Sets the port condition. Value sets up a

test for equal, and value sets up a test for not equal. An input

of a port with a condition will only succeed when the condition

matches. SETD is used to set the test operand.

IE_MODE_EVENT,

IE_MODE_INTERRUPT

Mode bits x. Sets the resource to generate events (value

) or interrupts (value ). By default it generates events.

DRIVE_DRIVE,

DRIVE_PULL_DOWN,

DRIVE_PULL_UP

Mode bits x. Sets the drive mode of the port. Value

sets the drive transistor to just drive the high side and enable a

weak pull-down, Value sets the drive transistors to just drive

the low side and enable a weak pull-up

MODE_SETPADCTRL

Mode bits x6. Sets the pad options according to the value

of bits

..8. Bits

and 8 set the pull resistor (

for none;

for weak pull-up;

for weak pull-down; or

for weak bus-

keep.). Bits

and

set the drive strength (

for mA;

for 8mA; or

for mA). Bit

enables slew-rate

control. Bit

enables the Schmitt-Trigger.

RUN_CLRBUF

Mode bits x, value : clears the port buffer

MS_MASTER,

MS_SLAVE

Mode bits x. Sets the port to master mode (value ) or

slave mode (value ).

BUF_NOBUFFERS,

BUF_BUFFERS

Mode bits x. Sets the port to be buffered (value ) or

unbuffered (value ). Unbuffered is the default.

RDY_NOREADY,

RDY_STROBED,

RDY_HANDSHAKE

Mode bits x. Sets the port to use data strobes (value )

or full handshaking (value ). Default is no ready wires.

SDELAY_NOSDELAY,

SDELAY_SDELAY

Mode bits x. Sets the port to optionally capture data on

the falling edge (value )

PORT_DATAPORT,

PORT_CLOCKPORT,

PORT_READYPORT

Mode bits x. Sets the port to be a clock (value ) or ready

signal (value ). By default the port is a data port. This can only

be applied to -bit ports.

INV_NOINVERT,

INV_INVERT

Mode bits x6. Sets the port to optionally invert the signal

(value ).

PAD_DELAY

Mode bits x, value must be in the range ... Delays the

input signals by a set number of core clock ticks. Defaults to .

Timers

There are

timers. The following controls can be set using SETC:
