R/W These bits select the input mode of the POE0 pin
00: Accept request on falling edge of POE0 input
01: Accept request when POE0 input has been sampled
for 16 Pφ/8 clock pulses, and all are low level.
10: Accept request when POE0 input has been sampled
for 16 Pφ/16 clock pulses, and all are low level.
11: Accept request when POE0 input has been sampled
for 16 Pφ/128 clock pulses, and all are low level.
* The write value should always be 0.
Output Level Control/Status Register (OCSR): The output level control/status register (OCSR)
is a 16-bit readable/writable register that controls the enable/disable of both output level
comparison and interrupts, and indicates status. If the OSF bit is set to 1, the high current pins
become high impedance.

Description
Output Short Flag
This flag indicates that any one pair of the three pairs of 2
phase outputs compared have simultaneously become
low level outputs.
Clear condition:
• By writing 0 to OSF after reading an OSF = 1
Set condition:
• When any one pair of the three 2-phase outputs
simultaneously become low level
Reserved
These bits are always read as 0. These bits should
always be written with 0
