Description
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 10.43, 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
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. These bits should
always be written with 0.
