11.2 GPT Registers and Address Map
11-2
The GPT programming model consists of a configuration register (GPTMCR), parallel
I/O registers (DDRGP, PORTGP), capture/compare registers (TCNT, TCTL1, TCTL2,
TIC[1:3], TOC[1:4], TI4/O5, CFORC), pulse accumulator registers (PACNT, PACTL),
pulse-width modulation registers (PWMA, PWMB, PWMC, PWMCNT, PWMBUFA,
PWMBUFB), status registers (TFLG1, TFLG2) and interrupt control registers (TMSK1,
TMSK2). Functions of the module configuration register are discussed in
Modes of Operation
ter functions are discussed in the appropriate sections.
All registers can be accessed using byte or word operations. Certain capture/compare
registers and pulse-width modulation registers must be accessed by word operations
to ensure coherency. If byte accesses are used to read a register such as the timer
counter register (TCNT), there is a possibility that data in the byte not being accessed
will change while the other byte is read. Both bytes must be accessed at the same
time.
The modmap (MM) bit in the system integration module configuration register
(SIMCR) defines the most significant bit (ADDR23) of the IMB address for each regis-
ter in the MCU. Because the CPU16 drives ADDR[23:20] to the same logic state as
ADDR[19:0], MM must equal one.
