Macro Definition Documentation

◆ tn_p32_soft_isr

#define tn_p32_soft_isr (   vec)

Interrupt handler wrapper macro for software context saving.

Usage looks like the following:

tn_p32_soft_isr(_TIMER_1_VECTOR)
{
   INTClearFlag(INT_T1);

   //-- do something useful
}

Note that you should not use __ISR(_TIMER_1_VECTOR) macro for that.

Parameters
vecinterrupt vector number, such as _TIMER_1_VECTOR, etc.

Definition at line 344 of file tn_arch_pic32.h.

◆ tn_p32_srs_isr

#define tn_p32_srs_isr (   vec)

Interrupt handler wrapper macro for shadow register context saving.

Usage looks like the following:

tn_p32_srs_isr(_INT_UART_1_VECTOR)
{
   INTClearFlag(INT_U1);

   //-- do something useful
}

Note that you should not use __ISR(_INT_UART_1_VECTOR) macro for that.

Parameters
vecinterrupt vector number, such as _TIMER_1_VECTOR, etc.

Variable Documentation

◆ tn_p32_int_nest_count

volatile int tn_p32_int_nest_count

current interrupt nesting count.

Used by macros tn_p32_soft_isr() and tn_p32_srs_isr().

◆ tn_p32_user_sp

void* tn_p32_user_sp

saved task stack pointer.

Needed when switching stack pointer from task stack to interrupt stack.

◆ tn_p32_int_sp

void* tn_p32_int_sp

saved ISR stack pointer.

Needed when switching stack pointer from interrupt stack to task stack.
