This is a preliminary specification and is subject to change.
19. Three-Phase Motor Control Timer Function
19.2.7 Timer B2 Interrupt Generation Frequency Set Counter (ICTB2)
Timer B2 Interrupt Generation Frequency Set Counter

Symbol
ICTB2
Address

Function
When a setting value is n, timer B2 interrupt is generated
every nth count timer B2 underflow meets the condition
selected by bits INV01 and INV00.
No register bits. If necessary, set to 0
After Reset
Undefined
Setting Range

Use the MOV instruction to set the ICTB2 register.
If the INV01 bit in the INVC0 register is set to 1, set the ICTB2 register when the TB2S bit in the TABSR
register is set to 0 (timer B2 counter stopped). If the INV01 bit is set to 0 and the TB2S bit to 1 (timer B2
counter start), do not set the ICTB2 register when timer B2 underflows.
When bits INV01 and INV00 are 11b, the first interrupt is generated when timer B2 underflows n-1 times
if a setting value in the ICTB2 counter is n. Subsequent interrupts are generated every n times timer B2
underflows.
