Timer Interface Module A (TIMA-6)
22.9.3 TIMA Counter Modulo Registers
Technical Data
NOTE:
The read/write TIMA modulo registers contain the modulo value for the
TIMA counter. When the TIMA counter reaches the modulo value, the
overflow flag (TOF) becomes set, and the TIMA counter resumes
counting from $0000 at the next clock. Writing to the high byte
(TAMODH) inhibits the TOF bit and overflow interrupts until the low byte
(TAMODL) is written. Reset sets the TIMA counter modulo registers.
Reset the TIMA counter before writing to the TIMA counter modulo
registers.
