R10–R13: R1 output port data register (FF46H)
Set the output data for the output ports.
When "1" is written: High level output
When "0" is written: Low level output
Reading: Valid
The output port terminals output the data written in the corresponding data registers without changing
it. When "1" is written to the register, the output port terminal goes high (VDD), and when "0" is written,
the output port terminal goes low (VSS).
When the output ports R12 and R13 are used for special output (TOUT, FOUT), fix the R12 register and
the R13 register at "1".
At initial reset, these registers are all set to "1".
PTOUT: TOUT output control register (FFC1HD2)
Controls the TOUT output.
When "1" is written: TOUT output ON
When "0" is written: TOUT output OFF
Reading: Valid
By writing "1" to the PTOUT register when the R12 register has been set to "1", the TOUT signal is output
from the R12 terminal. When "0" is written, the R12 terminal goes high (VDD).
When using the R12 output port for DC output, fix this register at "0".
At initial reset, this register is set to "0".
FOUTE: FOUT output control register (FF06HD3)
Controls the FOUT output.
When "1" is written: FOUT output ON
When "0" is written: FOUT output OFF
Reading: Valid
By writing "1" to the FOUTE register when the R13 register has been set to "1" , an FOUT signal is output
from the R13 terminal. When "0" is written, the R13 terminal goes high (VDD).
When using the R13 output port for DC output, fix this register at "0".
At initial reset, this register is set to "0".
