Description

OCE

R/W

Output Level Compare Enable

This bit enables the start of output level comparisons.

When setting this bit to 1, pay attention to the output pin

combinations shown in table 8.43, Mode Transition

Combinations. When 0 is output, the OSF bit is set to 1

at the same time when this bit is set, and output goes to

high impedance. Accordingly, bits 15 to 11 and bit 9 of

the port E data register (PEDR) are set to 1. For the

MTU output comparison, set the bit to 1 after setting the

MTU's output pins with the PFC. Set this bit only when

using pins as outputs.

When the OCE bit is set to 1, if OIE = 0 a high-

impedance request will not be issued even if OSF is set

to 1. Therefore, in order to have a high-impedance

request issued according to the result of the output level

comparison, the OIE bit must be set to 1. When OCE =

1 and OIE = 1, an interrupt request will be generated at

the same time as the high-impedance request:

however, this interrupt can be masked by means of an

interrupt controller (INTC) setting.

0: Output level compare disabled

1: Output level compare enabled; makes an output high

impedance request when OSF = 1.

Output Short Interrupt Enable

This bit makes interrupt requests when the OSF bit of

the OCSR is set.

0: Interrupt requests disabled

1: Interrupt request enabled

Reserved

These bits are always read as 0. The write value should

always be 0.

Note:

The write value should always be 0.
