CHAPTER 2 PIN FUNCTIONS
60
Preliminary User’s Manual U16031EJ2V1UD
(12) PDH0 to PDH15 (Port DH) 3-state I/O
PDH0 to PDH15 function as an 8- or 16-bit I/O port that can be set to input or output in 1-bit units.
Besides functioning as a port, in control mode, these pins operate as real-time pulse unit (RPU) I/O, PWM
output, data bus (D16 to D31), and external interrupt request input.
The operation mode can be set to port or control mode in 1-bit units, specified by the port DH mode control
register (PMCDH).
(a) Port mode
PDH0 to PDH15 can be set to input or output in 1-bit units using the port DH mode register (PMDH).
(b) Control mode
PDH0 to PDH15 can be set to port or control mode in 1-bit units using the PMCDH register.
(i)
INTPD0 to INTPD15 (Interrupt request from peripherals) input
These are external interrupt request input pins.
(ii) TOC4, TOC5 (Timer output) output
These are pulse signal output pins of timers C4 and C5.
(iii) INTP100, INTP101, INTP110, INTP111 (Timer capture trigger input) input
These are external capture trigger input pins of timers ENC10 and ENC11.
(iv) TIUD10, TIUD11 (Timer count pulse input) input
These are external count clock input pins of timers ENC10 and ENC11.
(v) TCUD10, TCUD11 (Timer control pulse input) input
These are external count clock input pins of timers ENC10 and ENC11.
(vi) TCLR10, TCLR11 (Timer clear) input
These are clear signal input pins of timers ENC10 and ENC11.
(vii) TO10, TO11 (Timer output) output
These are pulse signal output pins of timers ENC10 and ENC11.
(viii) PWM0, PWM1 (Pulse width modulation) output
These pins output the PWM pulse signal.
(ix) D16 to D31 (Data) 3-state I/O
These pins constitute a data bus for when the external memory is accessed. These are the higher
16-bit I/O bus pins of the 32-bit data.
The output changes in synchronization with the rise of the BUSCLK signal in the T1 state.
(13) PLLSEL (PLL operating mode select) input
This is an input pin used to specify the PLL operating mode.
(14) PLLVDD (PLL power supply)
This is an 1.5 V positive power supply pin for PLL synthesizer.
