问 下面是一个用用TIMERA的CCR1，CCR2，分别产生75%，25%的PWM信号的程序，用ACLK 做时钟源，但是老是出现警告“Warning[Pe001]: last line of file ends without a newline”
，不知道为什么，快把我烦死了，各位能帮忙看看吗？是个在TI上面下载的EXAMPLE
// MSP-FET430P140 Demo - Timer_A PWM TA1-2 upmode, 32kHz ACLK
//
// Description; This program will generate a two PWM outputs on P1.2/1.3 using
// Timer_A in an upmode. The value in CCR0, defines the period and the
// values in CCR1 and CCR2 the duty PWM cycles. Using 32kHz ACLK as TACLK,
// the timer period is 15.6ms with a 75% duty cycle on P1.2 and 25% on P1.3.
// ACLK = TACLK = LFXT1 = 32768, MCLK = SMCLK = default DCO ~ 800kHz.
// Normal mode LPM3
// /External watch crystal installed on XIN XOUT is required for ACLK
//
// MSP430F149
// -----------------
// /|\| XIN|-
// | | | 32k
// --|RST XOUT|-
// | |
// | P1.2|--> CCR1 - 75% PWM
// | P1.3|--> CCR2 - 25% PWM
