Output Compare Module Registers

This section describes the configuration and functions of the registers used by the
output compare operation. The output compare module has the two types of registers
shown below.
■ Compare Register (OCCP0 to OCCP7)
The bit configuration of the compare register (OCCP0 to OCCP7) is shown below.

Note: The MB91F353A/351A/352A/353A have two output compare channels (OCCP0 and OCCP2), but
do not have OCCP1 and OCCP3 to OCCP7.
The compare register is 16 bits, and its value is compared with the value of the 16-bit free-running timer.
Because the initial value of the compare register is undefined, be sure to set a value in it before enabling
output compare. The output compare register must be accessed in 16-bit or 32-bit units. If the value of the
compare register matches the value of the 16-bit free-running timer, a compare signal is generated and the
output compare interrupt flag is set. If the corresponding OTE bit of the port function register (PFR0) is set
to enable output, the output level corresponding to the compare register is reversed.
■ Output Control Register (OCS0 to OCS7)
The bit configuration of the output control register (OCS0 to OCS7) is shown below.
OCP01, 23, 45, 67
Address : 0000F6

0000F4

Only the output control registers for channels 0 and 1 are explained here. For details of the output control
registers for channels 2 to 7, when reading, replace channel number 0 with channel number 2, 4, or 6, and
channel number 1 with channel number 3, 5, or 7.
