Capture/Compare

Control

These registers control th e functions of the

capture/compare channels. EPA1_CON and

EPA3_CON require an extra byte because they

contain an additional bit for PWM rem ap mod e.

These two registers must be addressed as words;

the others can be addressed a s bytes.

Capture/Compare Time

In capture mode, these registers contain the

captured timer value. In compare mod e, these

registers contain the time at which an event is to

occur. In capture mode, these registers are

buffered to allow two captures before an overrun

occurs. However, they are not buffered in compare

mode.

INT_MASK 0008H 0008H 0008H Interrupt Mask

The bits in this 8-bit re gister enable and disab le

(mask) the interrupts associated wi th the corre-

sponding bits in the INT_P END register.

INT_MASK1 0013H 0013H 0013H Interrupt Mask 1

The bits in this 8-bit re gister enable and disab le

(mask) the interrupts associated wi th the corre-

sponding bits in the INT_PEND1 register.
