Bits[5:4] MDIV[1:0] Each bit selects an XTI divider. When either bit is low, an XTI divide-by-1 function is
selected. When either bit is HIGH, an XTI divide-by-2 function is selected. With both bits HIGH, XTI is divid-
ed by 4.
The table below shows the composite XTI division using both CLKMODE and MDIV[1:0].

Default: 0xFF, no overflows have occurred.
Note: This register interacts with Register 03h, the Overflow Mask Register.
The Overflow Status Register is used to indicate an individual overflow in a channel. If an overflow condition
on any channel is detected, the corresponding bit in this register is asserted (low) in addition to the open
drain active low OVFL pin going low. Each overflow status bit is sticky and is cleared only when read, pro-
viding full interrupt capability.

Default: 0xFF, all overflow interrupts enabled.
The Overflow Mask Register is used to allow or prevent individual channel overflow events from creating
activity on the OVFL pin. When a particular bit is set low in the Mask register, the corresponding overflow
bit in the Overflow Status register is prevented from causing any activity on the OVFL pin.
