Broadcast Pulse Generator Timer Register
The value in this register is compared to that of the internal Broadcast Pulse Generator
Counter. When they are equal, a broadcast interrupt pulse is generated and the counter is reset
to 0. The value in this register determines the broadcast interrupt pulse width in
approximately 30-ns increments. Due to the required glitch filters on the VMEbus IRQ[1]I_
and IRQ[2]I_ signal lines, the value written to this register must be greater than 0x0003.
Approximately, the broadcast interrupt pulse width is programmable from 120 ns to 1.97 ms.
After power-up, this register is initialized to 0x0022 which produces a 1.02-
broadcast pulse mode is enabled. Writing a value of all zeros to this register has no effect.
