5-16 Neuron C Compiler Errors (NCC)

NCC# Description

115 Pins IO_5...IO_7 must use ‘mux’ timer [NCC#115]

For I/O object types that use a timer/counter, the timer/counter used

is dependent on the pin assigned to the I/O object. There are two

timer/counters, the dedicated (abbreviated ded) and the multiplexed

(abbreviated mux). The dedicated circuit uses pin IO_1 for output

and pin IO_4 for input. The multiplexed circuit uses pin IO_0 for

output and multiplexes among pins IO_4, IO_5, IO_6, and IO_7 for

input.

For input objects using a timer/counter, the programmer need not

specify which timer/counter circuit is being used except when the

input I/O object is assigned to pin IO_4. Then, either the mux or

ded keyword must be included in the declaration of the I/O object.

116 I/O object requires ‘sync’ pin specification [NCC#116]

The triac I/O object type declaration must include an assignment for

a sync pin. Since the triac type uses a timer/counter output, the

sync pin must use a corresponding input on the same timer/counter.

If the dedicated timer/counter is used, only IO_4 can be used for the

sync pin. If the multiplexed timer/counter is used, any of IO_4,

IO_5, IO_6, or IO_7 can be used.

117 I/O object requires ‘sync’ pin on one of IO_4...IO_7 [NCC#117]

The neurowire I/O object type declaration must also include

specification of a pin to be used for an I/O object select. Only a pin

from IO_0 through IO_7 may be used for a select pin.

118 I/O object requires ‘sync’ pin on IO_4 [NCC#118]

The neurowire I/O object type declaration must also include

specification of a pin to be used for an I/O object select. Only a pin

from IO_0 through IO_7 may be used for a select pin.

119 I/O object requires ‘select’ pin specification [NCC#119]

The neurowire I/O object type declaration must also include

specification of a pin to be used for an I/O object select. Only a pin

from IO_0 through IO_7 may be used for a select pin.

120 The ‘select’ pin must be one of IO_0...IO_7 [NCC#120]

The neurowire I/O object type declaration must also include

specification of a pin to be used for an I/O object select. Only a pin

from IO_0 through IO_7 may be used for a select pin.

121 I/O object requires ‘master’, ‘slave’, or ‘slave_b’ [NCC#121]

The parallel I/O object type declaration must be qualified with one

of the keywords master, slave, or slave_b to specify which parallel

I/O protocol is to be used.

122

123

I/O object type not available on requested pin [NCC#122]

Pin/resource conflict with a previous I/O object [NCC#123]

In several cases, more than one Neuron Chip I/O object type can be

assigned to a single pin within a single application. The rules for

overlaying I/O object declarations are discussed in Chapter 2 of the

Neuron C Programmer's Guide.
