Description

Implementation of Timer 4 update interrupt service routine. If TIM4_UPD interrupt is enabled, interrupt service routine TIM4_UPD_ISR() is automatically called after timer is updated on period match.

Notes:

• TIM4_UPD_ISR() is used for internal time-keeping functions, and is called every 1ms
• user function can be attached to TIM4_UPD_ISR() via attachInterruptMillis()
• global interrupts must also be enabled, see interrupts()

Inclusion

• defined in stm8_interrupt_vector.h
• auto-loaded in main_general.h
• in config.h set #define USE_TIM4_UPD_ISR
