7.1.16 I/O Port Registers – PTA ~ PTF (0x14 ~ 0x19)
PTX can be operated by related instructions, as any other general purpose registers.
That is, PTX is an 8-bit, bidirectional, general purpose port. Its corresponding I/O
control bit determines the data direction of a PTX pin.
7.1.17 16-bit Free Run Counter (FRC) – LFRC (0x1A), HFRC (0x1B)
& LFRCB (0x1C)
R1A is 16-bit FRC low byte; R1B is high byte; R1C is low byte buffer.
7.1.18 Serial Peripheral Interface Read Register – SPIRB (0x1D)
Register R1D indicates SPI received data.
7.1.19 Serial Peripheral Interface Write Register – SPIWB (0x1E)
Register R1E indicates SPI transmitted data.
7.1.20 ADC Converting Value – ADDATA (0x1F)
ADDATA: Converting Value of ADC.

7.1.21 PWM Duty – DT0L (0x21)/DT0H (0x22) & DT1L (0x27) / DT1H
(0x28)
R22 : R21 16-bit PWM0 output duty cycle. R28 : R27 16-bit PWM1 output duty cycle.
7.1.22 PWM Period – PRD0L (0x23)/PRD0H (0x24) & PRD1L
(0x29)/PRD1H (0x2A)
R24 : R23 16-bit PWM0 output period cycle. R2A : R29 16-bit PWM1 output period
cycle.
