Carrier Modulator Transmitter (CMT)
Modulator
MC68HC05RC16 — Rev. 3.0
General Release Specification
Carrier Modulator Transmitter (CMT)
EIMSK — External Interrupt Mask
The external interrupt mask bit is used to mask IRQ and keyscan
interrupts. This bit is cleared by reset.
1 = IRQ and keyscan interrupts masked
0 = IRQ and keyscan interrupts enabled
EXSPC — Extended Space Enable
For a description of the extended space enable bit, see 9.5.3
Extended Space Operation. This bit is cleared by reset.
1 = Extended space enabled
0 = Extended space disabled
BASE — Baseband Enable
When set, the BASE bit disables the carrier generator and forces the
carrier output high for generation of baseband protocols. When BASE
is clear, the carrier generator is enabled and the carrier output toggles
at the frequency determined by values stored in the carrier data
registers. See 9.5.1 Time Mode. This bit is cleared by reset. This bit
is not double buffered and should not be written to during a
transmission.
1 = Baseband enabled
0 = Baseband disabled
MODE — Mode Select
For a description of CMT operation in time mode, see 9.5.1 Time
FSK Mode. This bit is cleared by reset. This bit is not double buffered
and should not be written to during a transmission.
1 = CMT operates in FSK mode.
0 = CMT operates in time mode.
IE — Interrupt Enable
A CPU interrupt will be requested when EOC is set if IE was
previously set. If IE is clear, EOC will not request a CPU interrupt.
1 = CPU interrupt enabled
0 = CPU interrupt disabled
