Output Level Control/Status Register (OCSR)

The output level control/status register (OCSR) is a 16-bit read/write 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.

OCSR is initialized to H'0000 by an external power-on reset; however, it is not initialized for

manual resets, reset by WDT standby mode, or sleep mode, so the previous data is maintained.

• Bit 15—Output Short Flag (OSF): This flag indicates that among the three pairs of 2 phase

outputs compared, the outputs of at least one pair have simultaneously become Low level

output.

Bit 15: OSF

Description

Clear condition: By writing 0 to OSF after reading an OSF = 1 (initial value)

Set condition: When any one pair of the 2-phase outputs simultaneously

become Low level

• Bits 14–10—Reserved: These bits always read as 0. The write value should always be 0.
