Register Timer data register 0n (TDR0nH, TDR0nL)
Timer input TI00 to TI03
Timer output TO00 to TO03, output controller
Control registers <Registers of unit setting block>
• Peripheral enable register 0 (PER0)
• Timer clock select register 0 (TPS0)
• Timer channel enable status register 0 (TE0, TEH0)
• Timer channel start register 0 (TS0, TSH0)
• Timer channel stop register 0 (TT0, TTH0)
• Timer output enable register 0 (TOE0)
• Timer output register 0 (TO0)
• Timer output level register 0 (TOL0)
• Timer output mode register 0 (TOM0)
<Registers of each channel>
• Timer mode register 0n (TMR0nH, TMR0nL)
• Timer status register 0n (TSR0n)
• Noise filter enable register 1 (NFEN1)
• Input switch control register (ISC)
• Port mode control register 0 (PMC0)
• Port mode register 0, 4 (PM0, PM4)

Remark n: Channel number
n = 0, 1 (for 10-pin products); n = 0 to 3 (for 16-pin products)
Alternate port for timer I/O of the timer array unit channels varies depending on products.
Table 6-2. Timer I/O Pins in the Products
Timer array unit channel 10-pin products 16-pin products
Channel 0 P03/TO00, P137/TI00 P03/TO00, P137/TI00
Channel 1 P04/TI01/TO01, (P40/TI01/TO01) P04/TI01/TO01, (P40/TI01/TO01)
Channel 2 — P05/TI02/TO02
Channel 3 — P41/TI03, P07/TO03
Remarks 1. If a pin is to be used for both timer input and timer output, it can be used only for timer input or timer
output.
2. —: Not supported
3. The pin names in parentheses indicate function-multiplexed ports while PIOR0 bit in the peripheral I/O
redirection register is set to 1.
