Base timer i

(1) Free-running operation

(RST2 to RST0 bits in the GiBCR1 register are set to "0002")

OUTCij pin

POijR bit

i=2 to 3, j=0 to 7

m : Setting value of the GiPOj register (000016 to FFFF16)

POijR bit : Bits in the IIO3IR to IIO11IR registers

The above applies to the following conditions.

The IVL bit in the GiPOCRj register is set to "0" (output "L" as an initial value). The INV

bit is set to "0" (no output inversed).

RST2 to RST0 bits in the GiBCR1 register are set to "0002" (no base timer reset).

(2) The base timer is reset when the base timer matches the GiPO0 register

(The RST1 bit is set to "1" and both RST0 and RST2 bits are set to "0")

i=2 to 3, j=1 to 7

m : Setting value of the GiPOj register (000016 to FFFF16)

n: Setting value of the GiPO0 register (000116 to FFFD16)

POijR bit : Bits in the IIO0IR to IIO11IR registers

The above applies to the following condition.

The IVL bit in the GiPOCRj register is set to "0" (output "L" as an initial value). The INV

bit is set to "0" (no output inversed).
