• Manufacturer Part Number: ST92141
• Description: 8/16-bit Mcu For 3-phase Ac Motor Control
• Manufacturer: STMicroelectronics

INDUCTION MOTOR CONTROLLER (Cont’d)
DEAD TIME GENERATOR REGISTER (DTG)
R254 - Read/Write
Register Page: 48
Reset Value: 0011 1111 (3Fh)
Bit 7:6 = Reserved.
Bit 5:0 = DTG[5:0] Dead time generator value (N) .
The delay is N x INTCLK period multiplied by 2.
If N = 0 the delay is 0.

Bit 7:4 = V[3:0]: Interrupt Vector Base Address .
User programmable interrupt vector bits.
The most significant nibble of the interrupt vector
address is given by V[3:0]. The other nibble is giv-
en by W[3:0] where W[0] is forced to ‘0’ and W[3:1]
are set by hardware according to the
terrupt Source
Table 26. Interrupt Source Address
Bit 3 = NMI: Non Maskable Interrupt pending bit.
This bit is set by hardware when an NMI event oc-
curs and the NMIE bit = 1. The NMI bit can be
cleared by software. It cannot be set by software.
As long as this bit is ‘1’ the NMI signal to ST9 is
kept active (high level).
0: No NMI pending
1: NMI pending
Note: As long as the external NMI signal is active
the NMI bit can not be reset.
Bit 2:0 = PL[2:0]: Priority level for the peripheral
interrupt.
