10.1.3 Pin Configuration
Table 10-1 summarizes the input and output pins of the 8-bit timer module.
Table 10-1 Input and Output Pins of 8-Bit Timer
Channel Name Symbol I/O Function
0 Timer output pin 0 TMO0 Output Outputs at compare match
Timer clock input pin 0 TMCI0 Input Inputs external clock for counter
Timer reset input pin 0 TMRI0 Input Inputs external reset to counter
1 Timer output pin 1 TMO1 Output Outputs at compare match
Timer clock input pin 1 TMCI1 Input Inputs external clock for counter
Timer reset input pin 1 TMRI1 Input Inputs external reset to counter
10.1.4 Register Configuration
Table 10-2 summarizes the registers of the 8-bit timer module.
Table 10-2 8-Bit Timer Registers
Channel Name Abbreviation R/W Initial value Address
*
1
0 Timer control register 0 TCR0 R/W H'00 H'FFB0
Timer control/status register 0 TCSR0 R/(W)
*
2
H'00 H'FFB2
Time constant register A0 TCORA0 R/W H'FF H'FFB4
Time constant register B0 TCORB0 R/W H'FF H'FFB6
Timer counter 0 TCNT0 R/W H'00 H'FFB8
1 Timer control register 1 TCR1 R/W H'00 H'FFB1
Timer control/status register 1 TCSR1 R/(W)

H'10 H'FFB3
Time constant register A1 TCORA1 R/W H'FF H'FFB5
Time constant register B1 TCORB1 R/W H'FF H'FFB7
Timer counter 1 TCNT1 R/W H'00 H'FFB9
All Module stop control register MSTPCR R/W H'3FFF H'FF3C
Notes: 1. Lower 16 bits of the address
2. Only 0 can be written to bits 7 to 5, to clear these flags.
Each pair of registers for channel 0 and channel 1 is a 16-bit register with the upper 8 bits for
channel 0 and the lower 8 bits for channel 1, so they can be accessed together by a word transfer
instruction.
