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
0 Timer output pin 0
Timer clock input pin 0
Timer reset input pin 0
1 Timer output pin 1
Timer clock input pin 1
Timer reset input pin 1
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
0 Timer control register 0
Timer control/status register 0 TCSR0
Time constant register A0
Time constant register B0
Timer counter 0
1 Timer control register 1
Timer control/status register 1 TCSR1
Time constant register A1
Time constant register B1
Timer counter 1
All Module stop control register
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.
